Public bug reported:
A script cannot call lxc-start-ephemeral and get a named container in a
reliable, race-free way.
Having the caller specify a name directly is racy, since the name could
have been taken in between checking that it doesn't exist already and
calling lxc-start-ephemeral.
Allowing lxc-start-ephemeral allows it to take care of the mkdir (and
retries) to generate an LXC container name in a race free manner, but
this needs -d to return the name in a machine-readable way, so that we
can create ephemeral LXC containers from scripts.
Please add a machine-readable mechanism to "lxc-start-ephemeral -d" and
then we can modify adt-virt-lxc to use it.
