Public bug reported:
When trying to restore a btrfs snapshot, it is renamed as-is. When
snapshots are created read-only (which is good practice), then reboot
will fail for a read-only root file system.
I suggest to create a child read-write snapshot instead. This has the following
advantages
- target snapshot is read-write
- source snapshot can be used multiple times in case something goes wrong
A snapshot can be created via:
mv @ @apt-old-root-DATE
btrfs subvolume snapshot $SNAPSHOT @
