Hello !
I performed a rollback about a month ago, and since then, the corresponding snapshot (853) has remained in my list of snapshots.
sudo snapper ls

I tried to delete it, but I then realized that the system is actually using that snapshot.
mount | grep 'on / '
/dev/nvme0n1p2 on / type btrfs (rw,noatime,ssd,discard=async,space_cache=v2,subvolid=1131,subvol=/@/.snapshots/853/snapshot)
Is this the expected behavior? Will that snapshot stay indefinitely until the next rollback? Will it eventually be cleaned up automatically?
Thanks.
