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

In context, this means that installing distributions and managing them - is handled slightly differently compared to traditional BIOS systems. - </p> - - <p> - On most systems, the /boot partition has to be left unencrypted while the others are encrypted. - This is so that GRUB, and therefore the kernel, can be loaded and executed since the firmware - can't open a LUKS volume. Not so with libreboot! Since GRUB is already included directly as a - payload, even /boot can be encrypted. This protects /boot from tampering by someone with physical - access to the machine. - </p> - - <p> - Boot Parabola's install environment. <a href="grub_boot_installer.html">How to boot a GNU/Linux installer</a>. - </p> - - <p> - For this guide I used the 2013 09 01 image to boot the live installer and install the system. - </p> - - <p> - Parabola is much more flexible than Trisquel, but also more involved to setup. Use Parabola. It's 10 million times better than Trisquel. - </p> - - <p> - Firstly if you use an SSD, beware there are issues with TRIM (not enabled through luks) and security issues if you do enable it. - See <a href="https://wiki.archlinux.org/index.php/Dm-crypt/Specialties#Discard.2FTRIM_support_for_solid_state_drives_.28SSD.29">this page</a> - for more info. - </p> - - <p> - <b>If you are using an SSD for this, make sure it's brand-new (or barely used). Or, otherwise, be sure that it never previously - contained plaintext copies of your data.</b> - </p> - - <p> - Wipe the MBR (if you use MBR):<br/> - # <b>lsblk</b><br/> - Your HDD is probably /dev/sda: - # <b>dd if=/dev/zero of=/dev/sda bs=446 count=1; sync</b><br/> - Never use SeaBIOS! The MBR section can easily be changed with malicious code, which SeaBIOS will blindly execute. - This guide is for libreboot with GRUB-as-payload only. - </p> - - <p> - Securely wipe the drive:<br/> - # <b>dd if=/dev/urandom of=/dev/sda; sync</b><br/> - NOTE: If you have an SSD, only do this the first time. If it was already LUKS-encrypted before, - use the info below to wipe the LUKS header. Also, check online for your SSD what the recommended - erase block size is. For example if it was 2MiB:<br/> - # <b>dd if=/dev/urandom of=/dev/sda bs=2M; sync</b> - </p> - <p> - If your drive was already LUKS encrypted (maybe you are re-installing your distro) then - it is already 'wiped'. You should just wipe the LUKS header. - <a href="https://www.lisenet.com/2013/luks-add-keys-backup-and-restore-volume-header/">https://www.lisenet.com/2013/luks-add-keys-backup-and-restore-volume-header/</a> - showed me how to do this. It recommends to do the first 3MiB. Now, that guide is recommending putting zero there. I'm doing to use urandom. Do this:<br/> - # <b>head -c 3145728 /dev/urandom > /dev/sda; sync</b><br/> - (wiping the LUKS header is important, since it has hashed passphrases and so on. It's 'secure', but 'potentially' a risk). - </p> - <p> - <b> - If you do plan to use an SSD, make sure to read - <a href="https://wiki.archlinux.org/index.php/Solid_State_Drives">https://wiki.archlinux.org/index.php/Solid_State_Drives</a><br/> - Edit /etc/fstab later on when chrooted into your install. Also, read the whole article and keep all points in mind, adapting - them for this guide. - </b> - </p> - - <p> - This guide will go through the installation steps taken at the time of writing, which may or may not change due to - the volatile nature of Parabola (it changes all the time). In general most of it should remain the same. If you spot mistakes, - please say so! This guide will be ported to the Parabola wiki at a later date. For up to date Parabola install guide, go to - the Parabola wiki. This guide essentially cherry picks the useful information (valid at the time of writing: 2014-09-15). - </p> - - <h2> - Change keyboard layout - </h2> - <p> - Parabola live shell assumes US Qwerty. If you have something different, use:<br/> - # <b>loadkeys LAYOUT</b><br/> - For me, LAYOUT would have been dvorak-uk. - </p> - - <h2>Getting started</h2> - <p> - The beginning is based on <a href="https://wiki.parabolagnulinux.org/Installation_Guide">https://wiki.parabolagnulinux.org/Installation_Guide</a>. - Then I referred to <a href="https://wiki.archlinux.org/index.php/Partitioning">https://wiki.archlinux.org/index.php/Partitioning</a> at first. - </p> - - <h2>dm-mod</h2> - <p> - device-mapper will be used - a lot. Make sure that the kernel module is loaded:<br/> - # <b>modprobe dm-mod</b> - </p> - - <h2>Create LUKS partition</h2> - <p> - I am using MBR partitioning, so I use cfdisk:<br/> - # <b>cfdisk /dev/sda</b> - </p> - <p> - I create a single large sda1 filling the whole drive, leaving it as the default type 'Linux' (83). - </p> - <p> - Now I refer to <a href="https://wiki.archlinux.org/index.php/Dm-crypt/Drive_preparation#Partitioning">https://wiki.archlinux.org/index.php/Dm-crypt/Drive_preparation#Partitioning</a>:<br/> - I am then directed to <a href="https://wiki.archlinux.org/index.php/Dm-crypt/Device_encryption">https://wiki.archlinux.org/index.php/Dm-crypt/Device_encryption</a>. - </p> - <p> - Parabola forces you to RTFM. - </p> - <p> - It tells me to run:<br/> - # <b>cryptsetup benchmark</b> (for making sure the list below is populated)<br/> - Then:<br/> - # <b>cat /proc/crypto</b><br/> - This gives me crypto options that I can use. It also provides a representation of the best way to setup LUKS (in this case, security is a priority; speed, a distant second). - To gain a better understanding, I am also reading:<br/> - # <b>man cryptsetup</b> - </p> - <p> - Following that page, based on my requirements, I do the following based on - based on <a href="https://wiki.archlinux.org/index.php/Dm-crypt/Device_encryption#Encryption_options_for_LUKS_mode">https://wiki.archlinux.org/index.php/Dm-crypt/Device_encryption#Encryption_options_for_LUKS_mode</a>. - Reading through, it seems like Serpent (encryption) and Whirlpool (hash) is the best option. - </p> - <p> - I am initializing LUKS with the following:<br/> - # <b>cryptsetup -v --cipher serpent-xts-plain64 --key-size 512 --hash whirlpool --use-random --verify-passphrase luksFormat /dev/sda1</b> - -- choose a <b>secure</b> passphrase here. Ideally lots of lowercase/uppercase numbers, letters, symbols etc all in a random pattern. The password - length should be as long as you are able to handle without writing it down or storing it anywhere. 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.
