@ -18,17 +18,17 @@ The partition layout I use rallows us to replicate the behavior found in openSUS
1. Snapper rollback <number> works! You will no longer need to manually rollback from a live USB like you would with the @ and @home layout suggested in the Arch Wiki.
2. You can boot into a readonly snapshot! GDM and other services will start normally so you can get in and verify that everything works before rolling back.
3. Automatic snapshots on pacman install/update operations
4. /boot/grub and /boot/efi are 2 seperate subvolumes which will not be rolled back with snapper. The kernel and initramfs are part of the snapshot.
4. /boot and /boot/efi are 2 seperate subvolumes which will not be rolled back with snapper.
5. For consistency with pacman's database, I deviate from SUSE's partition layout leave /usr/local/ and /opt as part of the snapshot. When you rollback, everything in those 2 directories rollback as well.
6. GRUB will boot into the default BTRFS snapshot set by snapper. Like on SUSE, your running system will always be a read-write snapshot in @/.snapshots/X/snapshot.
### Changes to the original project
1. Enabled AppArmor
1. Encrypted /boot (This was previously present on EasyArch, but Tommaso changed his script to use LUKS2 and have unencrypted /boot. Personally I would not do this, since encrypting /boot is the only way to protect the initramfs from being tampered with. GRUB will only validate the kernel if Secure Boot is used, not the initramfs).
2. SUSE - like partition layout
3. Snapper snapshots & rollback
4. Default umask to 077
5. Firewalld is enabled by default
6. Minimally setup GNOME 40
6. Minimally setup GNOME 40 with pipewire
7. Better mount options
