I have limited scripting skills, but I do my best.

Right now -B btrfs creates a subvolume for $lxc_path/$lxc_name/rootfs.
And earlier in this thread we agreed, that $lxc_path/$lxc_name would be better.

Of course the same for zfs.


So not the rootfs, but the path used as $lxc_name. Yes, you can always assume it's a mountpoint.
If not, it's just ot -B zfs, but something else.. -B dir or whatever is the default.

ps. Be aware, there can be mountpoints under rootfs, eg.:


zfs create -o mountpoint=/var/lib/lxc/CONTAINER tank/lxc/CONTAINER
zfs create -o mountpoint=/var/lib/lxc/CONTAINER/rootfs/var/mail tank/lxc/CONTAINER/mail


Do you plan to support this case?


Thanks,
