"should" I'm not going to get into... However, the DHCP clients usually
have a configuration file you can edit to tell it not to mess with the
resolv.conf settings.

Of course, if /var/ is not local, then the DHCP client can't very well
write to it before DHCP's run and /var's been mounted.

Actually, I do wonder what the behaviour in /etc/resolv.conf is if you've
got two DHCPing interfaces... And in the routing table, for that matter.
