That's a delay to wait after the container as reached RUNNING state.

So lxc-start will generate a list of all containers it needs to start,
sort them by lxc.start.order, then spawn the first one, check it reaches
RUNNING, when it does, wait <lxc.start.delay> seconds before continuing
with the next one.

Multiple entries, that's why I called it lxc.group and not lxc.groups.

The command line parameter (-g) is comma separate however. So commas
should be documented as invalid for a group name and so is "any" which
is a special group matching all containers.
