I'm taking this off bug-followup for now.

I'm not sure I do understand this correct, but this doesn't solve the
problem I described.

With this patch, the ipaddr. configuration of the vnet jail is still
done from outside and not by the rc scripts inside the jail!

_afterstart is way too late for doing the ip-configuration because
services inside the jail are already started.

_earlypoststart makes no sense to me, it is still run during the wrong time.
