This appears to me to break if you don't have a writable root; /var
will get mounted, but normally one runs dhclient before that happens.

The basic problem, as I see it here, is that dhclient uses /var,
but dhclient is generally run from netstart.local, and /var is not
mounted until *after* netstart (which calls netstart.local) is run.

Now I can fix half the problem with some code I'm going to put in
to /etc/rc mount all local (ffs, basically) critical filesystems
before netstart is run. However, if your /var is an NFS filesystem...
