Documentation: *major* cleanup.
Cleanup was long overdue. Old structure was messy and inefficient.

This is also beneficial because development - is now being done on Parabola, where Trisquel is no longer used by the maintainer - at the time of writing. - </p> - - <p> - It details configuration steps that I took after installing the base system, - as a follow up to <a href="encrypted_parabola.html">encrypted_parabola.html</a>. - This guide is likely to become obsolete at a later date (due to the volatile - 'rolling-release' model that Arch/Parabola both use), but attempts will be made to maintain it. - </p> - - <p> - <b> - This guide was valid on 2014-09-21. If you see any changes that should to be made at the present date, please get in touch - with the libreboot project! - </b> - </p> - - <p> - You do not necessarily have to follow this guide word-for-word; <i>parabola</i> is extremely flexible. - The aim here is to provide a common setup that most users will be happy with. While Parabola - can seem daunting at first glance (especially for new GNU/Linux users), with a simple guide it can provide - all of the same usability as Trisquel, without hiding any details from the user. - </p> - - <p> - Paradoxically, as you get more advanced Parabola can actually become <i>easier to use</i> - when you want to setup your machine in a special way compared to what most distributions provide. - You will find over time that other distributions tend to <i>get in your way</i>. - </p> - - <p> - <b> - This guide assumes that you already have Parabola installed. If you have not yet installed Parabola, - then <a href="encrypted_parabola.html">this guide</a> is highly recommended! - </b> - </p> - - <p> - A lot of the steps in this guide will refer to the Arch wiki. Arch is the upstream distribution that Parabola uses. - Most of this guide will also tell you to read wiki articles, other pages, manuals, and so on. In general it tries - to cherry pick the most useful information but nonetheless you are encouraged to learn as much as possible. - <b>It might take you a few days to fully install your system how you like, depending on how much you need to read. Patience is key, - especially for new users</b>. - </p> - - <p> - The Arch wiki will sometimes use bad language, such as calling the whole system Linux, using the term open-source (or closed-source), - and it will sometimes recommend the use of proprietary software. You need to be careful about this when reading anything on the - Arch wiki. - </p> - - <p> - Some of these steps require internet access. I'll go into networking later but for now, I just connected - my machine to a switch and did:<br/> - # <b>systemctl start dhcpcd.service</b><br/> - You can stop it later by running:<br/> - # <b>systemctl stop dhcpcd.service</b><br/> - For most people this should be enough, but if you don't have DHCP on your network then you should setup your network connection first:<br/> - <a href="#network">Setup network connection in Parabola</a> - </p> - -<hr/> - - <h2 id="pacman_configure">Configure pacman</h2> - <p> - pacman (<b>pac</b>kage <b>man</b>ager) is the name of the package management system in Arch, which Parabola - (as a deblobbed parallel effort) also uses. Like with 'apt-get' on debian-based systems like Trisquel, - this can be used to add/remove and update the software on your computer. - </p> - <p> - Based on <a href="https://wiki.parabolagnulinux.org/Installation_Guide#Configure_pacman">https://wiki.parabolagnulinux.org/Installation_Guide#Configure_pacman</a> - and from reading <a href="https://wiki.archlinux.org/index.php/Pacman">https://wiki.archlinux.org/index.php/Pacman</a> (make sure to read and understand this, - it's very important) and - <a href="https://wiki.parabolagnulinux.org/Official_Repositories">https://wiki.parabolagnulinux.org/Official_Repositories</a> - </p> - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - <h3 id="pacman_update">Updating Parabola</h3> - <p> - In the end, I didn't change my configuration for pacman. When you are updating, resync with the latest package names/versions:<br/> - # <b>pacman -Syy</b><br/> - (according to the wiki, -Syy is better than Sy because it refreshes the package list even if it appears to be up to date, - which can be useful when switching to another mirror).<br/> - Then, update the system:<br/> - # <b>pacman -Syu</b> - </p> - <p> - <b> - Before installing packages with 'pacman -S', always update first, using the notes above. - </b> - </p> - <p> - Keep an eye out on the output, or read it in /var/log/pacman.log. Sometimes, pacman will show messages - about maintenance steps that you will need to perform with certain files (typically configurations) - after the update. Also, you should check both the Parabola and Arch home pages to see if they mention any issues. - If a new kernel is installed, you should also update to be able to use it (the currently running kernel will - also be fine). It's generally good enough to update Parabola once every week, or maybe twice. As a - rolling release distribution, it's a good idea never to leave your install too outdated; update regularly. This - is simply because of the way the project works; old packages are deleted from the repositories quickly, once they are updated. - A system that hasn't been updated for quite a while will mean potentially more reading of previous posts through the website, - and more maintenance work. - </p> - <p> - The Arch forum can also be useful, if others have the same issue as you (if you encounter issues, that is). Parabola's - IRC channel (#parabola on freenode) can also help you. - </p> - <p> - Due to this and the volatile nature of Parabola/Arch, you should only update when you have at least a couple hours of spare time - in case of issues that need to be resolved. You should never update, for example, if you need your system for an important event, - like a presentation or sending an email to an important person before an allocated deadline, and so on. - </p> - <p> - Relax - packages are well-tested regularly when new updates are made to the repositories. Separate 'testing' repositories - exist for this exact reason. Despite what many people will tell you, Parabola is fairly stable and trouble-free, - so long as you are aware of how to check for issues, and are willing to spend some time fixing issues in - the rare event that they do occur. - </p> - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - <h3 id="pacman_maintain">Maintaining Parabola</h3> - <p> - Parabola is a very simple distro, in the sense that you are in full control - and everything is made transparent to you. One consequence is - that you also need to know what you are doing, and what you have done before. In general, keeping notes (such as what I have done - with this page) can be very useful as a reference in the future (if you wanted to re-install it or install the distro - on another computer, for example). - </p> - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - <h4 id="pacman_cacheclean">Cleaning the package cache</h4> - <p> - <b> - The following is very important as you continue to use, update and maintain your Parabola system:<br/> - <a href="https://wiki.archlinux.org/index.php/Pacman#Cleaning_the_package_cache">https://wiki.archlinux.org/index.php/Pacman#Cleaning_the_package_cache</a>. - Essentially, this guide talks about a directory that has to be cleaned once in a while, to prevent it from growing too big (it's a cache - of old package information, updated automatically when you do anything in pacman). - </b> - </p> - <p> - To clean out all old packages that are cached:<br/> - # <b>pacman -Sc</b> - </p> - <p> - The wiki cautions that this should be used with care. For example, since older packages are deleted from the repo, - if you encounter issues and want to revert back to an older package then it's useful to have the caches available. - Only do this if you are sure that you won't need it. - </p> - <p> - The wiki also mentions this method for removing everything from the cache, including currently installed packages that are cached:<br/> - # <b>pacman -Scc</b><br/> - This is inadvisable, since it means re-downloading the package again if you wanted to quickly re-install it. This should only be used - when disk space is at a premium. - </p> - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - <h4 id="pacman_commandequiv">pacman command equivalents</h4> - <p> - The following table lists other distro package manager commands, and their equivalent in pacman:<br/> - <a href="https://wiki.archlinux.org/index.php/Pacman_Rosetta">https://wiki.archlinux.org/index.php/Pacman_Rosetta</a> - </p> - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - - <h3 id="yourfreedom">your-freedom</h3> - <p> - your-freedom is a package specific to Parabola, and it is installed by default. What it does is conflict with packages - from Arch that are known to be non-free (proprietary) software. When migrating from Arch (there is a guide on the Parabola - wiki for migrating - converting - an existing Arch system to a Parabola system), installing - your-freedom will also fail if these packages are installed, citing them as conflicts; the recommended solution - is then to delete the offending packages, and continue installing <i>your-freedom</i>. - </p> - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - -<hr/> - - <h2 id="useradd">Add a user</h2> - <p> - Based on <a href="https://wiki.archlinux.org/index.php/Users_and_Groups">https://wiki.archlinux.org/index.php/Users_and_Groups</a>. - </p> - <p> - It is important (for security reasons) to create and use a non-root (non-admin) user account for every day use. The default 'root' account is intended - only for critical administrative work, since it has complete access to the entire operating system. - </p> - <p> - Read the entire document linked to above, and then continue. - </p> - <p> - Add your user:<br/> - # <b>useradd -m -G wheel -s /bin/bash <i>yourusername</i></b><br/> - Set a password:<br/> - # <b>passwd <i>yourusername</i></b> - </p> - - <p><a href="#pagetop">Back to top of page</a></p> - -<hr/> - - <h2 id="systemd">systemd</h2> - <p> - This is the name of the system used for managing services in Parabola. It is a good idea to become familiar with it. - Read <a href="https://wiki.archlinux.org/index.php/systemd">https://wiki.archlinux.org/index.php/systemd</a> - and <a href="https://wiki.archlinux.org/index.php/systemd#Basic_systemctl_usage">https://wiki.archlinux.org/index.php/systemd#Basic_systemctl_usage</a> - to gain a full understanding. <b>This is very important! Make sure to read them.</b> - </p> - <p> - An example of a 'service' could be a webserver (such as lighttpd), or sshd (openssh), dhcp, etc. There are countless others. - </p> - <p> - <a href="https://bbs.archlinux.org/viewtopic.php?pid=1149530#p1149530">https://bbs.archlinux.org/viewtopic.php?pid=1149530#p1149530</a> explains - the background behind the decision by Arch (Parabola's upstream supplier) to use systemd. - </p> - - <p> - The manpage should also help:<br/> - # <b>man systemd</b><br/> - The section on 'unit types' is especially useful. - </p> - - <p> - According to the wiki, systemd 'journal' keeps logs of a size up to 10% of the total size your / partition takes up. - on a 60GB root this would mean 6GB. That's not exactly practical, and can have performance implications later when the - log gets too big. Based on instructions from the wiki, I will reduce the total size of the journal to 50MiB (the wiki - recommends 50MiB). - </p> - <p> - Open /etc/systemd/journald.conf and find the line that says:<br/> - <i>#SystemMaxUse=</i><br/> - Change it to say:<br/> - <i>SystemMaxUse=50M</i> - </p> - <p> - The wiki also recommended a method for forwarding journal output to TTY 12 (accessible by pressing ctrl+alt+f12, - and you use ctrl+alt+[F1-F12] to switch between terminals). I decided not to enable it. - </p> - <p> - Restart journald:<br/> - # <b>systemctl restart systemd-journald</b> - </p> - - <p> - The wiki recommends that if the journal gets too large, you can also simply delete (rm -rf) everything inside /var/log/journald/* - but recommends backing it up. This shouldn't be necessary, since you already set the size limit above and systemd will automatically - start to delete older records when the journal size reaches it's limit (according to systemd developers). - </p> - - <p> - Finally, the wiki mentions 'temporary' files and the utility for managing them.<br/> - # <b>man systemd-tmpfiles</b><br/> - The command for 'clean' is:<br/> - # <b>systemd-tmpfiles --clean</b><br/> - According to the manpage, this <i>"cleans all files and directories with an age parameter"</i>. - According to the Arch wiki, this reads information in /etc/tmpfiles.d/ and /usr/lib/tmpfiles.d/ - to know what actions to perform. Therefore, it is a good idea to read what's stored in these locations - to get a better understanding. - </p> - <p> - I looked in /etc/tmpfiles.d/ and found that it was empty on my system. However, /usr/lib/tmpfiles.d/ contained some files. - The first one was etc.conf, containing information and a reference to this manpage:<br/> - # <b>man tmpfiles.d</b><br/> - Read that manpage, and then continue studying all of the files. - </p> - <p> - The systemd developers tell me that it usually isn't necessary to touch the systemd-tmpfiles utility manually at all. - </p> - - <p><a href="#pagetop">Back to top of page</a></p> - -<hr/> - - <h2 id="interesting_repos">Interesting repositories</h2> - <p> - Parabola wiki at <a href="https://wiki.parabolagnulinux.org/Repositories#kernels">https://wiki.parabolagnulinux.org/Repositories#kernels</a> - mentions about a repository called [kernels] for custom kernels that aren't in the default base. It might be worth looking into what is available - there, depending on your use case. - </p> - <p> - I enabled it on my system, to see what was in it. Edit /etc/pacman.conf and below the 'extra' section add:<br/> - <i> - [kernels]<br/> - Include = /etc/pacman.d/mirrorlist - </i> - </p> - <p> - Now sync with the repository:<br/> - # <b>pacman -Syy</b> - </p> - <p> - List all available packages in this repository:<br/> - # <b>pacman -Sl kernels</b> - </p> - <p> - In the end, I decided not to install anything from it but I kept the repository enabled regardless. - </p> - <p><a href="#pagetop">Back to top of page.</a></p> - -<hr/> - - <h2 id="network">Setup a network connection in Parabola</h2> - <p> - Read <a href="https://wiki.archlinux.org/index.php/Configuring_Network">https://wiki.archlinux.org/index.php/Configuring_Network</a>. - </p> - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - <h3 id="network_hostname">Set the hostname</h3> - <p> - This should be the same as the hostname that you set in /etc/hostname when installing Parabola. You can also do it with systemd (do so now, if you like):<br/> - # <b>hostnamectl set-hostname <i>yourhostname</i></b><br/> - This writes the specified hostname to /etc/hostname. More information can be found in these manpages:<br/> - # <b>man hostname</b><br/> - # <b>info hostname</b><br/> - # <b>man hostnamectl</b> - </p> - <p> - Add the same hostname to /etc/hosts, on each line. Example:<br/> - <i> - 127.0.0.1 localhost.localdomain localhost <u>myhostname</u><br/> - ::1 localhost.localdomain localhost <u>myhostname</u> - </i> - </p> - <p> - You'll note that I set both lines; the 2nd line is for IPv6. More and more ISP's are providing this now (mine does) - so it's good to be forward-thinking here. - </p> - <p> - The <i>hostname</i> utility is part of the <i>inetutils</i> package and is in core/, installed by default (as part of <i>base</i>). - </p> - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - <h3 id="network_status">Network Status</h3> - <p> - According to the Arch wiki, <a href="https://wiki.archlinux.org/index.php/Udev">udev</a> should already detect the ethernet chipset - and load the driver for it automatically at boot time. You can check this in the <i>"Ethernet controller"</i> section - when running this command:<br/> - # <b>lspci -v</b> - </p> - <p> - Look at the remaining sections <i>'Kernel driver in use'</i> and <i>'Kernel modules'</i>. In my case it was as follows:<br/> - <i> - Kernel driver in use: e1000e<br/> - Kernel modules: e1000e - </i> - </p> - <p> - Check that the driver was loaded by issuing <i>dmesg | grep module_name</i>. In my case, I did:<br/> - # <b>dmesg | grep e1000e</b> - </p> - <h3 id="network_devicenames">Network device names</h3> - <p> - According to <a href="https://wiki.archlinux.org/index.php/Configuring_Network#Device_names">https://wiki.archlinux.org/index.php/Configuring_Network#Device_names</a>, - it is important to note that the old interface names like eth0, wlan0, wwan0 and so on no longer apply.

Ideally, 100 characters or more. - It might take you a while to memorize a long passphrase before beginning this step. - </p> - - <h2>Create LVM</h2> - <p> - Now I refer to <a href="https://wiki.archlinux.org/index.php/LVM">https://wiki.archlinux.org/index.php/LVM</a>. - </p> - <p> - Open the LUKS partition:<br/> - # <b>cryptsetup open --type luks /dev/sda1 lvm</b><br/> - (it will be available at /dev/mapper/lvm)<br/> - I'm told that the above is old syntax, which is what I did anyway. You could also try:<br/> - # <b>cryptsetup luksOpen /dev/sda1 lvm</b> - </p> - <p> - Create LVM partition:<br/> - # <b>pvcreate /dev/mapper/lvm</b><br/> - Show that you just created it:<br/> - # <b>pvdisplay</b> - </p> - <p> - Now I create the volume group, inside of which the logical volumes will be created:<br/> - # <b>vgcreate matrix /dev/mapper/lvm</b> (volume group name is 'matrix')<br/> - Show that you created it:<br/> - # <b>vgdisplay</b> - </p> - <p> - Now create the logical volumes:<br/> - # <b>lvcreate -L 2G matrix -n swapvol</b> (2G swap partition, named <u>swapvol</u>)<br/> - # <b>lvcreate -l +100%FREE matrix -n rootvol</b> (single large partition in the rest of the space, named <u>rootvol</u>)<br/> - You can also be flexible here, for example you can specify a /boot, a /, a /home, a /var, a /usr, etc. For example, - if you will be running a web/mail server then you want /var in it's own partition (so that if it fills up with logs, it won't crash your system). - For a home/laptop system (typical use case), a root and a swap will do (really). - </p> - <p> - Verify that the logical volumes were created, using the following command:<br/> - # <b>lvdisplay</b> - </p> - - <h2>Create / and swap partitions</h2> - <p> - For the swapvol LV I use:<br/> - # <b>mkswap /dev/mapper/matrix-swapvol</b> - </p> - <p> - For the rootvol LV I use:<br/> - # <b>mkfs.ext4 /dev/mapper/matrix-rootvol</b> - </p> - - <h2>Continue with Parabola installation</h2> - <p> - Mount the root (/) partition:<br/> - # <b>mount /dev/matrix/rootvol /mnt</b><br/> - </p> - <p> - This guide is really about GRUB, Parabola and cryptomount. I have to show how to install Parabola - so that the guide can continue. - </p> - <p> - Now I am following the rest of <a href="https://wiki.parabolagnulinux.org/Installation_Guide">https://wiki.parabolagnulinux.org/Installation_Guide</a>. - I also also cross referencing <a href="https://wiki.archlinux.org/index.php/Installation_guide">https://wiki.archlinux.org/index.php/Installation_guide</a>. - </p> - <p> - Create /home and /boot on rootvol mountpoint:<br/> - # <b>mkdir /mnt/home</b><br/> - # <b>mkdir /mnt/boot</b> - </p> - <p> - The wiki says to enable the swap so that it can be detected by 'genfstab':<br/> - # <b>swapon /dev/matrix/swapvol</b> - </p> - <p> - DHCP was already working for me, so I had internet during the install. Therefore, I ignore the 'Connect to the Internet' section of the install guide. - I also ignore wifi, since I can set that up after the install. For now, I am just using ethernet. - Otherwise, refer to <a href="https://wiki.archlinux.org/index.php/Configuring_Network">https://wiki.archlinux.org/index.php/Configuring_Network</a>. - You can test to see if internet is already working by pinging a few domains. - </p> - - <p> - I commented out all lines except the Server line for the UK Parabola server (main server) in <b>/etc/pacman.d/mirrorlist</b> and then did:<br/> - # <b>pacman -Syy</b><br/> - # <b>pacman -Syu</b><br/> - # <b>pacman -Sy pacman</b> (and then I did the other 2 steps above, again)<br/> - In my case I did the steps in the next paragraph, and followed the steps in this paragraph again. - </p> - <p> - <troubleshooting><br/> - The following is based on 'Verification of package signatures' in the Parabola install guide.<br/> - Check there first to see if steps differ by now.<br/> - Now you have to update the default Parabola keyring. This is used for signing and verifying packages:<br/> - # <b>pacman -Sy parabola-keyring</b><br/> - It says that you you get GPG errors, it's probably an expired key so do:<br/> - # <b>pacman-key --populate parabola</b><br/> - # <b>pacman-key --refresh-keys</b><br/> - # <b>pacman -Sy parabola-keyring</b><br/> - To be honest, you should do the above anyway. Parabola has a lot of maintainers, and a lot of keys. Really!<br/> - Also, it says that if the clock is set incorrectly then you have to manually set the correct time <br/> - (if keys are listed as expired because of it):<br/> - # <b>date MMDDhhmm[[CC]YY][.ss]</b><br/> - I also had to install:<br/> - # <b>pacman -S archlinux-keyring</b><br/> - # <b>pacman-key --populate archlinux</b><br/> - In my case I saw some conflicting files reported in pacman, stopping me from using it.<br/> - I deleted the files that it mentioned - and then it worked. Specifically, I had this error:<br/> - <i>licenses: /usr/share/licenses/common/MPS exists in filesystem</i><br/> - I rm -rf'd the file and then pacman worked. I'm told that the following would have also made it work:<br/> - # <b>pacman -Sf licenses</b><br/> - </troubleshooting><br/> - </p> - <p> - I also like to install other packages (base-devel, compilers and so on) and wpa_supplicant/dialog are needed for wireless after the install:<br/> - # <b>pacstrap /mnt base base-devel wpa_supplicant dialog</b> - </p> - - <h3>Configure the system</h3> - <p> - From the Parabola installation guide (Arch's one was identical):<br/> - # <b>genfstab -p /mnt >> /mnt/etc/fstab</b> - </p> - <p> - Chroot into new system:<br/> - # <b>arch-chroot /mnt</b> - </p> - <p> - It's a good idea to have this installed:<br/> - # <b>pacman -S linux-libre-lts</b> - </p> - <p> - It was also suggested that you should install this kernel (read up on what GRSEC is):<br/> - # <b>pacman -S linux-libre-grsec</b> - </p> - <p> - This is another kernel that sits inside /boot, which you can use. LTS means 'long-term support'. These are so-called 'stable' kernels - that can be used as a fallback during updates, if a bad kernel causes issues for you. - </p> - <p> - Parabola does not have wget. This is sinister. Install it:<br/> - # <b>pacman -S wget</b> - </p> - <ul> - <li>Write your hostname to /etc/hostname</li> - <li> - Symlink /etc/localtime to /usr/share/zoneinfo/Zone/SubZone. Replace Zone and Subzone to your liking. For example: - <ul> - <li># <b>ln -s /usr/share/zoneinfo/Europe/London /etc/localtime</b></li> - </ul> - </li> - <li> - Set <a href="https://wiki.parabolagnulinux.org/Locale#Setting_system-wide_locale">locale</a> preferences in /etc/locale.conf. In my case, I did:<br/> - <i> - LANG="en_GB.UTF-8"<br/> - # Keep the default sort order (e.g. files starting with a '.'<br/> - # should appear at the start of a directory listing.)<br/> - LC_COLLATE="C"<br/> - # Set the short date to YYYY-MM-DD (test with "date +%c")<br/> - LC_TIME="en_GB.UTF-8" - </i> - </li> - <li> - Add <a href="https://wiki.parabolagnulinux.org/KEYMAP">console keymap and font</a> preferences in /etc/vconsole.conf. In my case:<br/> - <i> - KEYMAP=dvorak-uk<br/> - FONT=Lat2-Terminus16 - </i> - </li> - <li> - Uncomment the selected locale (same as what you specified in /etc/locale.conf) in /etc/locale.gen and generate it with: - <ul> - <li># <b>locale-gen</b></li> - </ul> - </li> - <li> - Configure /etc/mkinitcpio.conf as needed (see <a href="https://wiki.parabolagnulinux.org/Mkinitcpio">mkinitcpio</a>) - Specifically, for this use case:<br/> - <ul> - <li> - add <b>i915</b> to the MODULES array (forces the driver to load earlier, so that the consolefont isn't wiped out after getting to login).<br/> - add <b>encrypt</b> and <b>lvm2</b> in that order, before the 'filesystems' entry in the HOOKS array.<br/> - add <b>keymap</b>, <b>consolefont</b> and <b>shutdown</b> to the end of the HOOKS array in that order.<br/> - move <b>keyboard</b>, <b>keymap</b> and <b>consolefont</b> in that order, to go before 'encrypt' in the HOOKS array.<br/> - At the end your HOOKS array will look like this:<br/> - <i>HOOKS="base udev autodetect modconf block keyboard keymap consolefont encrypt lvm2 filesystems fsck shutdown"</i> - <ul> - <li>keymap adds to initramfs the keymap that you specified in /etc/vconsole.conf</li> - <li>consolefont adds to initramfs the font that you specified in /etc/vconsole.conf</li> - <li>encrypt adds LUKS support to the initramfs - needed to unlock your disks at boot time</li> - <li>lvm2 adds LVM support to the initramfs - needed to mount the LVM partitions at boot time</li> - <li>shutdown is needed according to Parabola wiki for unmounting devices (such as LUKS/LVM) during shutdown</li> - <li> - Runtime modules can be found in /usr/lib/initcpio/hooks, and build hooks can be found in - /usr/lib/initcpio/install. - </li> - <li><b>mkinitcpio -H hookname</b> gives information about each hook.</li> - </ul> - </li> - </ul> - </li> - <li> - Now using mkinitcpio, you can create the kernel and ramdisk for booting with (note, this is different than Arch, specifying linux-libre instead of linux):<br/> - # <b>mkinitcpio -p linux-libre</b><br/> - Also do it for linux-libre-lts:<br/> - # <b>mkinitcpio -p linux-libre-lts</b><br/> - Also do it for linux-libre-grsec:<br/> - # <b>mkinitcpio -p linux-libre-grsec</b> - </li> - </ul> - - <h3>Set a root password</h3> - <p> - At the time of writing, Parabola used SHA512 by default for it's password hashing. - </p> - <p> - I referred to <a href="https://wiki.archlinux.org/index.php/SHA_password_hashes">https://wiki.archlinux.org/index.php/SHA_password_hashes</a>. - </p> - <p> - Open /etc/pam.d/passwd and add rounds=65536 at the end of the uncommented 'password' line. - </p> - <p> - # <b>passwd root</b><br/> - Make sure to set a secure password! Also, it must never be the same as your LUKS password. - </p> - - <h3>Extra security tweaks</h3> - <p> - Based on <a href="https://wiki.archlinux.org/index.php/Security">https://wiki.archlinux.org/index.php/Security</a>. - </p> - <p> - Restrict access to important directories:<br/> - # <b>chmod 700 /boot /etc/{iptables,arptables}</b> - </p> - <p> - Lockout user after three failed login attempts:<br/> - Edit the file /etc/pam.d/system-login and comment out that line:<br/> - <i># auth required pam_tally.so onerr=succeed file=/var/log/faillog</i><br/> - Or just delete it. Above it, put:<br/> - <i>auth required pam_tally.so deny=2 unlock_time=600 onerr=succeed file=/var/log/faillog</i><br/> - To unlock a user manually (if a password attempt is failed 3 times), do:<br/> - # <b>pam_tally --user <i>theusername</i> --reset</b> - What the above configuration does is lock the user out for 10 minutes, if they make 3 failed login attempts. - </p> - <p> - Configure sudo - not covered here. Will be covered post-installation in another tutorial, at a later date. - If this is a single-user system, you don't really need sudo. - </p> - - <h3>Unmount, reboot!</h3> - <p> - Exit from chroot:<br/> - # <b>exit</b> - </p> - <p> - unmount:<br/> - # <b>umount /mnt</b><br/> - # <b>swapoff -a</b> - </p> - <p> - deactivate the lvm lv's:<br/> - # <b>lvchange -an /dev/matrix/rootvol</b><br/> - # <b>lvchange -an /dev/matrix/swapvol</b><br/> - </p> - <p> - Lock the encrypted partition (close it):<br/> - # <b>cryptsetup luksClose lvm</b> - </p> - <p> - # <b>shutdown -h now</b><br/> - Then boot up again. - </p> - - <h3>Booting from GRUB</h3> - <p> - Initially you will have to boot manually. Press C to get to the GRUB command line. The underlined parts are optional - (using those 2 underlines will boot lts kernel instead of normal). - </p> - <p> - grub> <b>cryptomount -a (ahci0,msdos1)</b><br/> - grub> <b>set root='lvm/matrix-rootvol'</b><br/> - grub> <b>linux /boot/vmlinuz-linux-libre<u>-lts</u> root=/dev/matrix/rootvol cryptdevice=/dev/sda1:root</b><br/> - grub> <b>initrd /boot/initramfs-linux-libre<u>-lts</u>.img</b><br/> - grub> <b>boot</b><br/> - </p> - <p> - You could also make it load /boot/vmlinuz-linux-libre-grsec and /boot/initramfs-linux-libre-grsec.img - </p> - -<hr/> - - <h2>Modify grub.cfg inside the ROM</h2> - - <p> - Now you need to modify the ROM, so that Parabola can boot automatically with this configuration. - <a href="grub_cbfs.html">grub_cbfs.html</a> shows you how. Follow that guide, using the configuration details below. - </p> - <p> - Inside the 'Load Operating System' menu entry, change the contents to:<br/> - <b><i> - cryptomount -a (ahci0,msdos1)<br/> - set root='lvm/matrix-rootvol'<br/> - linux /boot/vmlinuz-linux-libre<u>-lts</u> root=/dev/matrix/rootvol cryptdevice=/dev/sda1:root<br/> - initrd /boot/initramfs-linux-libre<u>-lts</u>.img - </i></b> - </p> - - <p> - Note: the underlined parts above (-lts) can also be removed, to boot the latest kernel instead of LTS (long-term support) kernels. - You could also copy the menu entry and in one have -lts, and without in the other menuentry. - You could also create a menu entry to load /boot/vmlinuz-linux-libre-grsec and /boot/initramfs-linux-libre-grsec.img - </p> - - <p> - Personally, I opted to have the entry for linux-libre-grsec at the top, so that it would load by default. - </p> - - <p> - Above the 'Load Operating System' menu entry you should also add a GRUB password, like so: - </p> -<pre><b><i>set superusers="root" -password_pbkdf2 root grub.pbkdf2.sha512.10000.711F186347156BC105CD83A2ED7AF1EB971AA2B1EB2640172F34B0DEFFC97E654AF48E5F0C3B7622502B76458DA494270CC0EA6504411D676E6752FD1651E749.8DD11178EB8D1F633308FD8FCC64D0B243F949B9B99CCEADE2ECA11657A757D22025986B0FA116F1D5191E0A22677674C994EDBFADE62240E9D161688266A711 -</i></b></pre> - - <p> - Note that the above entry specifies user 'root'; this is just a username for GRUB. You don't even need to use root. - Change root on both of those 2 lines to whatever you want. - </p> - - <p> - Start dhcp on ethernet:<br/> - # <b>systemctl start dhcpcd.service</b> - This is just for the step below. I won't cover network configuration here. That is for another Parabola article. - </p> - - <p> - The password hash (it's <b>password</b>, by the way) after <i>'password_pbkdf2 root'</i> <i>should be changed</i> and is created by the <b>grub-mkpasswd-pbkdf2</b> utility, which you need to install or otherwise compile, - like so:<br/> - # <b>pacman -S grub</b> - </p> - - <p> - GRUB isn't needed for booting, since it's already included as a payload in libreboot. This is only so that the utility needed becomes available. Get your hash - by entering your chosen password at the prompt, when running this command:<br/> - # <b>grub-mkpasswd-pbkdf2</b> - </p> - - <p> - It will output the hash for the password that you entered. Make sure to specify a password that is different from both your LUKS *and* your root/user password. - Use it to replace the default hash mentioned above. - </p> - - <p> - With this setup, you will have to enter a password at boot time, in GRUB, before being able to use any of the menu entries or switch to the terminal. - This protects your system from an attacker simply booting a live usb distro and re-flashing the boot firmware. - </p> - - <p> - You probably only need base-devel (compilers and so on) to build and use cbfstool. It was already installed if you followed this tutorial, but here it is:<br/> - # <b>pacman -S base-devel</b> - </p> - - <p> - For flashing the modified ROM, I just used flashrom from the Parabola repo's:<br/> - # <b>pacman -S flashrom</b><br/> - I also installed dmidecode:<br/> - # <b>pacman -S dmidecode</b> - </p> - - <p> - When done, deleted GRUB (remember, we only needed it for the <i>grub-mkpasswd-pbkdf2</i> utility; - GRUB is already part of libreboot, flashed alongside it as a <i>payload</i>):<br/> - # <b>pacman -R grub</b> - </p> - -<hr/> - - <p> - If you followed all that correctly, you should now have a fully encrypted Parabola installation. - This is a very barebones Parabola install (the default one). Refer to the wiki for how to do the rest - (desktop, etc). - </p> - -<hr/> - - <h2>Further security tips</h2> - <p> - <a href="https://wiki.archlinux.org/index.php/Security">https://wiki.archlinux.org/index.php/Security</a>.<br/> - <a href="https://wiki.parabolagnulinux.org/User:GNUtoo/laptop">https://wiki.parabolagnulinux.org/User:GNUtoo/laptop</a> - </p> - -<hr/> - - <h2>Follow-up tutorial: configuring Parabola</h2> - <p> - <a href="configuring_parabola.html">configuring_parabola.html</a> shows my own notes post-installation.

In my case, I use MBR partitioning so it's (ahci0,msdos1). - 'msdos' is GRUB's name simply because this partitioning type is traditionally used by MS-DOS. - It doesn't mean you have a proprietary OS. - </p> - - <p> - Trisquel doesn't keep the filenames of kernels consistent, instead it keeps old kernels and - new kernel updates are provided with the version in the filename. This can make GRUB payload - a bit tricky. Fortunately, there are symlinks /vmlinuz and /initrd.img - so if your /boot and / are on the same partition, you can set GRUB to boot from that. - These are also updated automatically when installing kernel updates from your distributions - apt-get repositories. - <b> - Note: when using <a href="http://jxself.org/linux-libre">jxself kernel releases</a>, - these are not updated at all and you have to update them manually. - </b> - </p> - - <p> - For the GRUB payload's grubtest.cfg (in the 'Load Operating System' menu entry), we therefore have (in this example):<br/> - <b>set root='ahci0,msdos1'</b><br/> - <b>linux /vmlinuz root=UUID=3a008e14-4871-497b-95e5-fb180f277951</b><br/> - <b>initrd /initrd.img</b> - </p> - - <p> - Optionally, you can convert the UUID to it's real device name, for example /dev/sda1 in this case. - sdX naming isn't very reliable, though, which is why UUID is used for most distributions. - </p> - - <p> - Alternatively, if your /boot is on a separate partition then you cannot rely on the /vmlinuz and /initrd.img symlinks. - Instead, go into /boot and create your own symlinks (update them manually when you install a new kernel update).<br/> - $ <b>sudo -s</b><br/> - # <b>cd /boot/</b><br/> - # <b>rm -rf vmlinuz initrd.img</b><br/> - # <b>ln -s <u>kernel</u> ksym</b><br/> - # <b>ln -s <u>initrd</u> isym</b><br/> - # <b>exit</b> - </p> - - <p> - Replace the underlined <b>kernel</b> and <b>initrd</b> filenames above with the actual filenames, of course. - </p> - - <p> - Then your grubtest.cfg menu entry (for payload) becomes like that, for example if / was on sda2 and /boot was on sda1:<br/> - <b>set root='ahci0,msdos1'</b><br/> - <b>linux /ksym root=/dev/sda2</b><br/> - <b>initrd /isym</b> - </p> - - <p> - There are lots of possible variations so please try to adapt. - </p> - - <h3 id="example_modifications_parabola">Parabola GNU/Linux-libre</h2> - - <p> - You can basically adapt the above.

If everyone (majority of people) use strong security by default, - it makes attacks more costly and time consuming; in effect, making them disappear. - </p> - <p> - This tutorial deals with reducing the number of devices that have direct memory access that - could communicate with inputs/outputs that could be used to remotely - command the machine (or leak data). - </p> - - <h1 id="procedure">Disassembly</h1> - - <p> - Remove those screws and remove the HDD:<br/> - <img src="t60_dev/0001.JPG" alt="" /> <img src="t60_dev/0002.JPG" alt="" /> - </p> - - <p> - Lift off the palm rest:<br/> - <img src="t60_dev/0003.JPG" alt="" /> - </p> - - <p> - Lift up the keyboard, pull it back a bit, flip it over like that and then disconnect it from the board:<br/> - <img src="t60_dev/0004.JPG" alt="" /> <img src="t60_dev/0005.JPG" alt="" /> <img src="t60_dev/0006.JPG" alt="" /> - </p> - - <p> - Gently wedge both sides loose:<br/> - <img src="t60_dev/0007.JPG" alt="" /> <img src="t60_dev/0008.JPG" alt="" /> - </p> - - <p> - Remove that cable from the position:<br/> - <img src="t60_dev/0009.JPG" alt="" /> <img src="t60_dev/0010.JPG" alt="" /> - </p> - - <p> - Now remove that bezel.

They might safe but could have - access to the computer's RAM trough DMA. If people have an intel - card(most T60's come with Intel wifi by default, until you change it),then that card runs - a non-free firwamre and has access to the computer's RAM trough DMA!

You don't need to remove these, but you can if you want - (to make it tidier after removing other parts). I removed the antenna wires, the modem jack, the modem cable and - also (on another model) a device inside the part where the wwan antenna goes (wasn't sure what it was, but I knew it wasn't needed). <b>This is optional</b> - </p> - - <p> - Remove the microphone (can desolder it, but you can also easily pull it off with you hands). Already removed here:<br/> - <img src="x60_security/0001_microphone.jpg" alt="" /><br/> - <b>Rationale:</b><br/> - Another reason to remove the microphone: If your computer gets<a href="#ref1">[1]</a> compromised, it can - record what you say, and use it to receive data from nearby devices if - they're compromised too. Also, we do not know what the built-in microcode (in the CPU) is doing; it could theoretically - be programmed to accept remote commands from some speaker somewhere (remote security hole). <b>In other words, - the machine could already be compromised from the factory.</b> - </p> - - <p> - Remove the modem:<br/> - <img src="x60_security/0001_modem.jpg" alt="" /><br/> - (useless, obsolete device) - </p> - - <p> - Remove the speaker:<br/> - <img src="x60_security/0001_speaker.jpg" alt="" /><br/> - Reason: combined with the microphone issue, this could be used to leak data.<br/> - If your computer gets<a href="#ref1">[1]</a> compromised, it can be used to - transmit data to nearby compromised devices. It's unknown if it can be - turned into a microphone<a href="#ref2">[2]</a>.<br/> - Replacement: headphones/speakers (line-out) or external DAC (USB). - </p> - - <p> - Remove the wlan (also remove wwan if you have it):<br/> - <img src="x60_security/0001_wlan_wwan.jpg" alt="" /><br/> - Reason: has direct (and very fast) memory access, and could (theoretically) leak data over a side-channel.<br/> - <b>Wifi:</b> The ath5k/ath9k cards might not have firmware at all. They might safe but could have - access to the computer's RAM trough DMA. If people have an intel - card(most X60's come with Intel wifi by default, until you change it),then that card runs - a non-free firwamre and has access to the computer's RAM trough DMA! So - it's risk-level is very high.<br/> - <b>Wwan (3d modem):</b> They run proprietary software and have access to the - computer's RAM! So it's like AMT but over the GSM network which is - probably even worse.<br/> - Replacement: external USB wifi dongle.

Also intel cards have - the capability to change a connector's function, for instance the - microphone jack can now become a headphone plug, that's called - retasking.

And it worked.<br/> - - Here is the pinout (correlate it with your programmer's documentation):<br/> - <img src="x60_unbrick/0017.jpg" alt="" /> - </p> - - <p> - My programmer, usb cable and clip:<br/> - <img src="x60_unbrick/0018.jpg" alt="" /><br/> - My programmer (bus pirate):<br/> - <img src="x60_unbrick/0019.jpg" alt="" /><br/> - My clip (pomona 5250):<br/> - <img src="x60_unbrick/0020.jpg" alt="" /><br/> - My USB mini a to b cable:<br/> - <img src="x60_unbrick/0021.jpg" alt="" /><br/> - Connecting the pomona:<br/> - <img src="x60_unbrick/0022.jpg" alt="" /><br/> - Connecting the USB cable from programmer to 2nd(working/non-bricked) computer, my T60:<br/> - <img src="x60_unbrick/0024.jpg" alt="" /><br/> - Programmer is now active:<br/> - <img src="x60_unbrick/0023.jpg" alt="" /><br/> - Now I install flashrom on the T60 (running Trisquel GNU/Linux) and do this:<br/> - <b>flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/x60/libreboot_usqwerty.rom</b><br/> - Note: there are also other ROM images for X60<br/> - Note: this is using buspirate as the programmer, so it is flashing the X60, not the T60!<br/> - Here's my terminal window on the T60:<br/> - <img src="x60_unbrick/0025.jpg" alt="" /><br/> - So, you should see the following:<br/> - -- - <pre> - flashrom v0.9.5.2-r1517 on Linux 3.2.0-61-generic (i686), built with libpci 3.1.8, GCC 4.6.3, little endian - flashrom is free software, get the source code at http://www.flashrom.org - - Calibrating delay loop... delay loop is unreliable, trying to continue OK. - Found Macronix flash chip "MX25L1605" (2048 kB, SPI) on buspirate_spi. - Reading old flash chip contents... done. - Erasing and writing flash chip...

running and you flashed another ROM; and you had bucts 1 set and - the ROM wasn't dd'd.* or if Lenovo BIOS was present and libreboot wasn't flashed.<br/><br/> - - In this case, unbricking is easy: reset BUC.TS to 0 by removing that yellow cmos coin (it's a battery) and putting it back after a minute or two:<br/> - <img src="x60t_unbrick/0008.JPG" alt="" /><br/><br/> - - *Those dd commands should be applied to all newly compiled X60 ROM's (the ROM's in libreboot binary archives already have this applied!):<br/> - dd if=coreboot.rom of=top64k.bin bs=1 skip=$[$(stat -c %s coreboot.rom) - 0x10000] count=64k<br/> - dd if=coreboot.rom bs=1 skip=$[$(stat -c %s coreboot.rom) - 0x20000] count=64k | hexdump<br/> - dd if=top64k.bin of=coreboot.rom bs=1 seek=$[$(stat -c %s coreboot.rom) - 0x20000] count=64k conv=notrunc<br/> - (doing this makes the ROM suitable for use when flashing a machine that still has Lenovo BIOS running, - using those instructions: <a href="http://www.coreboot.org/Board:lenovo/x60/Installation" target="_blank">http://www.coreboot.org/Board:lenovo/x60/Installation</a>. - </p> - - <h1 id="recovery">bad rom (or user error), machine won't boot</h1> - <p> - In this scenario, you compiled a ROM that had an incorrect configuration, or there is an actual bug preventing your machine from - booting. Or, maybe, you set BUC.TS to 0 and shut down after first flash while Lenovo BIOS was running. In any case, your machine is bricked and will not boot at all. - </p> - <p> - "Unbricking" means flashing a known-good (working) ROM. The problem: you can't boot the machine, making this difficult. In this situation, external hardware (see hardware requirements above) is needed which can flash the SPI chip (where libreboot resides). - </p> - - <p> - <img src="x60t_unbrick/0000.JPG" alt="" /> - </p> - - <p> - Remove those screws:<br/> - <img src="x60t_unbrick/0001.JPG" alt="" /> - </p> - - <p> - Remove the HDD:<br/> - <img src="x60t_unbrick/0002.JPG" alt="" /> - </p> - - <p> - Push keyboard forward to loosen it:<br/> - <img src="x60t_unbrick/0003.JPG" alt="" /> - </p> - - <p> - Lift:<br/> - <img src="x60t_unbrick/0004.JPG" alt="" /> - </p> - - <p> - Remove those:<br/> - <img src="x60t_unbrick/0005.JPG" alt="" /> - </p> - - <p> - - <img src="x60t_unbrick/0006.JPG" alt="" /> - </p> - - <p> - Also remove that (marked) and unroute the antenna cables:<br/> - <img src="x60t_unbrick/0007.JPG" alt="" /> - </p> - - <p> - Some X60T's you have to unroute those too:<br/> - <img src="x60t_unbrick/0010.JPG" alt="" /> - </p> - - <p> - Remove the LCD extend board screws. Also remove those screws (see blue marks) and remove/unroute the cables and remove the metal plate:<br/> - <img src="x60t_unbrick/0008.JPG" alt="" /> - </p> - - <p> - Remove that screw and then remove the board:<br/> - <img src="x60t_unbrick/0009.JPG" alt="" /> - </p> - - <p> - At this point, you should wire up your programmer according to it's documentation. For me, this was (see: "SparkFun cable pin reference"):<br/> - <a href="http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts" target="_blank">http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts</a>.<br/> - Correlating with the following information, I was able to wire up my pirate correctly:<br/> - <a href="http://flashrom.org/Bus_Pirate#Connections" target="_blank">http://flashrom.org/Bus_Pirate#Connections</a><br/> - And by following that advice:<br/> - <a href="http://www.coreboot.org/Board:lenovo/x60/Installation#Howto" target="_blank">http://www.coreboot.org/Board:lenovo/x60/Installation#Howto</a>.<br/> - Note: that last page says to wire up only those 5 pins (see below) like that: 1, 2, 4, 5, 6.<br/> - Note: and then, for power it says (on that coreboot.org page) to connect the power jack to the board and connect the - AC adapter (without powering on the board).<br/> - Note: I ignored that advice, and wired up all 8 pins. And it worked.<br/> - - Here is the pinout (correlate it with your programmer's documentation):<br/> - <img src="x60t_unbrick/0011.JPG" alt="" /><br/> - (SPI chip here is on the bottom of the board) - </p> - - <p> - Bus pirate:<br/> - <img src="x60_unbrick/0019.jpg" alt="" /> - </p> - - <p> - Pomona 5250:<br/> - <img src="x60_unbrick/0020.jpg" alt="" /> - </p> - - <p> - Connect pomona:<br/> - <img src="x60_unbrick/0022.jpg" alt="" /> - </p> - - <p> - Connect pirate to USB on 2nd computer:<br/> - <img src="x60_unbrick/0024.jpg" alt="" /> - </p> - - <p> - Pirate is active:<br/> - <img src="x60_unbrick/0023.jpg" alt="" /> - </p> - - <p> - <img src="x60_unbrick/0025.jpg" alt="" /> - </p> - - <p> - On the 2nd machine, I did: <b>flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/x60t/libreboot_ukqwerty.rom</b> - </p> - - <pre> - flashrom v0.9.5.2-r1517 on Linux 3.2.0-61-generic (i686), built with libpci 3.1.8, GCC 4.6.3, little endian - flashrom is free software, get the source code at http://www.flashrom.org - - Calibrating delay loop... delay loop is unreliable, trying to continue OK. - Found Macronix flash chip "MX25L1605" (2048 kB, SPI) on buspirate_spi. - Reading old flash chip contents... done. - Erasing and writing flash chip...
