At the moment I have a / partition with btrfs and /home partition with xfs. I would like to take advantage of btrfs snapshots for certain directories under /home, e.g. /home/robert/.wines . Apparently this doesn't work out of the box:
# btrfs subvolume create /home/robert/.wines Create subvolume '/home/robert/.wines' ERROR: cannot create subvolume - Inappropriate ioctl for device
Is there a way to create a subvolume under /home, which is not a btrfs mount?
