have no proof and don't mind if there are many pointers. Though this
doesn't look helpful to me as well.

I don't think it is always suiatable to do configuration later.
We had races in OpenVZ on VPS create/stop against exec/enter etc. (even
introduced flag is_running). So I have some experience to believe it
will be painfull place.
