I planning to make some changes like this:
echo " -B zfs [--zfs-root PATH]" >&2
echo " --zfs-root PATH specify the zfs path for lxcpath (default:
tank/lxc)" >&2
where tank used to be the default zfs pool name for.
A typical zfs list output is like this:
NAME USED AVAIL REFER MOUNTPOINT
tank 384G 710G 168K /tank
tank/lxc 384G 710G 256K /data/lxc
tank/lxc/camel 108G 710G 108G /data/lxc/camel
tank/lxc/common 854M 710G 854M /data/lxc/common
tank/lxc/confluence 5.84G 710G 5.84G /data/lxc/confluence
tank/lxc/demo 1.13G 710G 1.13G /data/lxc/demo
It's mount point was set by:
zfs set mountpoint=/data/lxc tank/lxc
Of course it's can be anywhere on the filesystem, eg. /var/lib/lxc.
Creating the filesystem for the container:
zfs create $zfs_root/$lxc_name
Cleanup:
zfs destroy $zfs_root/$lxc_name
I've never used neither lxc-clone nor zfs clone, but according to its manpage
it's not a rocket
science:)
I just wrote the things above, to make sure, I'm on the right way and maybe you
want to follow this
kind of setup:)
If you need help for testing, just let me know, if I'm capable, I can test it.

Good point!
