Right now if we say

	lxc-create -t ubuntu -n u1 -B zfs

that means make the rootfs be type zfs.  Where/how should it be
specified that $lxcpath/$lxcname should be a new zfs, not
$lxcpath/$lxcname/rootfs?  'zfs.mounttype = [whole | rootfs]' ?
Something like that would be ok for me, my main concern is actually
that the special casing in lxcapi_create() and lxcapi_destroy()
be done cleanly and concisely.  But yeah it should be possible.  Do
you mind sending a patch?
