Yeah, that can't work.  /dev/lxc1 is the path to the directory for the
vg but it's going to contain symlinks to the devmapper devices, not a
directory that can be copied into.  So that /dev/lxc1/ipa01-test" rootfs
path doesn't make sense...  But that rootfs value is passed to the
template from lxc-create.  In the case that it's not passed (which
should be never) it's an automatically generated path of
$cfg_dir/rootfs, which is obviously not the case here.

Just took a peek at the Ubuntu and the Oracle template and they're doing
the same thing.  The Oracle template has a little bit more in it for
btrfs subvolumes but that's a different story.

I think Serge or Stéphane is going to have to chime in on this because I
don't see how it's suppose to work.  There's something broken in the
setup of that rootfs path but I'm just not seeing it.
