Snapper's rollbacks work fine in Arch after a few tweaks:

1. Install snapper, grub-btrfs, snap-pac;
2. Enable grub-btrfsd.service;
3. Add the hook grub-btrfs-overlayfs at the end of HOOKS in /etc/mkinitcpio.conf;
4. Remove the subvol=... option from root's fstab entry;
5. Remove code that adds rootflags=subvol=... from /etc/grub.d/10_linux;
6. Rebuild the grub configuration with sudo grub-mkconfig -o /boot/grub/grub.cfg;
7. Take a snapshot with snapper create;
8. Rollback to the just created snapshot with snapper --ambit classic rollback ;
