Installing Trisquel GNU/Linux with full disk encryption (including /boot)

+ +
+ +

+ Because GRUB is installed directly as a payload of libreboot (or coreboot), you don't need an unencrypted /boot partition + when setting up an encrypted system. This means that your machine can really secure data while powered off. +

+ +

+ This works in Trisquel 7, and probably Trisquel 6. Boot the 'net installer' (Install Trisquel in Text Mode). How to boot a GNU/Linux installer. +

+ +

+ Set a strong user password (ideally above 40 characters, of lowercase/uppercase, numbers and symbols) and when the installer asks you to setup + encryption (ecryptfs) for your home directory, select 'Yes'. +

+ +

+ + Your user password should be different than the LUKS password which you will set later on. + Your LUKS password should, like the user password, be secure. + +

+ +

Partitioning

+ +

Choose 'Manual' partitioning:

+ + +

Further partitioning

+ +

+ Now you are back at the main partitioning screen. You will simply set mountpoints and filesystems to use. +

+ + +

Kernel

+ +

+ Installation will ask what kernel you want to use. linux-generic is fine. +

+ +

Tasksel

+ +

+ Just continue here, without selecting anything. You can install everything later (it's really easy). +

+ +

Install the GRUB boot loader to the master boot record

+ +

+ Choose 'Yes'. It will fail, but don't worry. Then at the main menu, choose 'Continue without a bootloader'. +

+ +

+ You do not need to install GRUB at all, since in libreboot you are using the GRUB payload (for libreboot) to boot your system directly. +

+ +

Clock UTC

+ +

+ Just say 'Yes'. +

+ +

+ Booting your system +

+ +

+ At this point, you will have finished the installation. At your GRUB payload, press C to get to the command line. +

+ +

+ Do that:
+ grub> cryptomount -a (ahci0,msdos1)
+ grub> set root='lvm/buzz-distro'
+ grub> linux /vmlinuz root=/dev/mapper/buzz-distro cryptdevice=/dev/mapper/buzz-distro:root quiet splash ro
+ grub> initrd /initrd.img
+ grub> boot +

+ +

+ ecryptfs +

+ +

+ Immediately after logging in, do that:
+ $ sudo ecryptfs-unwrap-passphrase +

+ +

+ This will be needed in the future if you ever need to recover your home directory from another system, so write it down and keep the note + somewhere secret. Ideally, you should memorize it and then burn the note (or not even write it down, and memorize it still)> +

+ +

+ Modify grub.cfg (CBFS) +

+ +

+ Now you need to set it up so that the system will automatically boot, without having to type a bunch of commands. +

+ +

+ Modify your grub.cfg (in the firmware) using this tutorial; + just change the default menu entry 'Load Operating System' to say this inside: +

+ +

+ cryptomount -a (ahci0,msdos1)
+ set root='lvm/buzz-distro'
+ linux /vmlinuz root=/dev/mapper/buzz-distro cryptdevice=/dev/mapper/buzz-distro:root quiet splash ro
+ initrd /initrd.img +

+ +

+ Additionally, you should set a GRUB password. This is not your LUKS password, but it's a password that you have to enter to see + GRUB. This protects your system from an attacker simply booting a live USB and re-flashing your firmware. This should be different than your LUKS passphrase and user password. +

+ +

+ The GRUB utility can be used like so:
+ $ grub-mkpasswd-pbkdf2 +

+ +

+ Give it a password (remember, it has to be secure) and it'll output something like:
+ grub.pbkdf2.sha512.10000.711F186347156BC105CD83A2ED7AF1EB971AA2B1EB2640172F34B0DEFFC97E654AF48E5F0C3B7622502B76458DA494270CC0EA6504411D676E6752FD1651E749.8DD11178EB8D1F633308FD8FCC64D0B243F949B9B99CCEADE2ECA11657A757D22025986B0FA116F1D5191E0A22677674C994EDBFADE62240E9D161688266A711 +

+ +

+ Put that in the grub.cfg (the one for CBFS inside the ROM) before the 'Load Operating System' menu entry like so (example):
+

+ 
+set superusers="root"
+password_pbkdf2 root grub.pbkdf2.sha512.10000.711F186347156BC105CD83A2ED7AF1EB971AA2B1EB2640172F34B0DEFFC97E654AF48E5F0C3B7622502B76458DA494270CC0EA6504411D676E6752FD1651E749.8DD11178EB8D1F633308FD8FCC64D0B243F949B9B99CCEADE2ECA11657A757D22025986B0FA116F1D5191E0A22677674C994EDBFADE62240E9D161688266A711
+
+ +

+ Obviously, replace it with the correct hash that you actually got for the password that you entered. Meaning, not the hash that you see above! +

+ +

+ After this, you will have a modified ROM with the menu entry for cryptomount, and the entry before that for the GRUB password. Flash the modified ROM + using this tutorial. +

+ +

+ Update Trisquel +

+ +

+ $ sudo apt-get update
+ $ sudo apt-get upgrade +

+ +

+ At the time of writing, Trisquel 7 had this + bug from upstream. The workaround identified in this page + was as follows:
+ $ sudo apt-get remove libpam-smbpass +

+ +

+ Install a desktop (optional) +

+ +

+ Installs the default desktop:
+ $ sudo apt-get install trisquel +

+ +

+ It might ask for postfix configuration. I just choose 'No configuration'. +

+ +

+ Next time you boot, it'll start lightdm and you can login. To start lightdm now, do:
+ $ sudo service lightdm start +

+ +

+ Go back to the terminal (ctrl-alt-f1) and exit:
+ $ exit +

+ +

+ Go back to lightdm (ctrl-alt-f7) and login. +

+ +

+ Since you installed using net install and you only installed the base system, network-manager isn't controlling + your eth0 but instead /etc/network/interfaces is. Comment out the eth0 lines in that file, and then do:
+ $ sudo /etc/init.d/networking stop
+ $ sudo service network-manager restart +

+ +

+ Conclusion +

+ +

+ If you followed all that correctly, you should now have a fully encrypted system. +
