Couldn't I make a snapshot via some other command than rollback?
Yes, you can make btrfs snapshot. Read "man btrfs-subvolume". It will not be visible in the snapper interface until you add necessary metadata. It will not be visible in the grub boot menu until you recreate it (after having created snapper metadata). You will also need to manually make it the default subvolume.
But if the goal is to just reboot into writable snapshot - you do not need snapper configuration, so "btrfs subvolume snapshot" + "btrfs subvolume set-default" will be enough.
The final option is to simply change the current snapshot to read-write. There are many reasons why one should not do it, but if you are desperate - see "man btrfs-property".
If the only other option is a new install, perhaps it i worth a shot. I'll give it a day or so of exploring further and then decide... -- Roger Oberholtzer
