On my old system, I had somehow (forgot how) set up the LXD containers and stuff to be inside a BTRFS subvolume.
I still have that subvolume, but formatted the rest of my hard disk (so installed LXD afresh).
How do I make LXD use the data from that BTRFS subvolume for LXD? I tried everything I could think of, but lxd init
complains that the btrfs subvol is not empty.
What should I do?
Thanks.
