I'm still not entirely happy with this, as I think there is a race
condition here.  NM kicks things off as soon as the ifcfg-* file is
written out, which is done as part of self.write() in network.py.  Just
after the ifcfg file is written, we try to construct the hosts file,
which relies on a working resolver.  We don't actually block on the
network being up before we do the lookups.

I think what we really need to do here is split out the writing of the
ifcfg-* file from the rest of the files, and wait until network is up
before writing out the rest of the files.  (actually writing out the
rest isn't really necessary during early network bring up I think, that
whole part can be delayed until the pre-install call where we write them
to the install filesystem).

David, what do you think?
