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.
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.

The **partitions layout** is pretty straightforward, it's inspired by [this section](https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system#Btrfs_subvolumes_with_swap) of the Arch Wiki. As you can see there's just a couple of partitions:
1. A **FAT32**, 100MiB sized, mounted at `/boot/efi` for the ESP.
