System Recovery

Issue in some core profiles like the systemd suite, or the desktop environment can fully break your system. This should not happen a lot, but if it does here is the process to recover your system on Archlinux:

1. Boot from a Archlinux live USB
2. If you root partition is encryped, decrypt it: cryptsetup open /dev/<your-disk-id> vg0
3. Mount your root partition: mount /dev/<your-plain-disk-id> /mnt
4. Chroot into your system: arch-chroot /mnt
5. Check the AppArmor messages to see what profile is faulty: aa-log
6. Temporarily fix the issue with either:
   • When only one profile is faultily, remove it: rm /etc/apparmor.d/<profile-name>
   • Otherwise, you can also remove the package: pacman -R apparmor.d
   • Alternatively, you may temporarily disable apparmor as it will allow you to boot and study the log: systemctl disable apparmor
7. Exit, unmount, and reboot:

   exit
   umount -R /mnt
   reboot
   

8. Create an issue and report the output of aa-log
