So if something went wrong in the rpm update or you want to revert to the prior copy of the OS/filesystem, you can boot back into the snapshot, using subvolid=256 as filesystem mount options for / in fstab.

If you want to just default to the snapshot then you can run btrfs subvol set-default 256 and you are just running from the old snapshot state going forward.
