lxc.start.order is not required unless you are doing strict prioritized
ordering.

Also be careful about lxc.group.  If your container is a member of any
group, it must also be a member of the "onboot" group or it will be
ignored by the scripts by default.  By default, the helper scripts will
start members of the "onboot" group first and then any containers that
are not a member of any group.  That too is configurable.

I would add...

lxc.group = onboot

Just to be sure.

I know it seems to be somewhat redundant to specify "lxc.start.auto = 1"
and "lxc.group = onboot" but it's there for some corner cases with group
memberships.
