Speaking of DHCP client and nameservers - I've recently been annoyed that
my commenting-out of the resolv.conf rewrite in dhclient-script is whacked
every time I do a make build. It seems like it would be *really* useful if
this (and other functions of dhclient-script) were configurable via
settings in rc.conf (I think dhclient-script has too much functionality in
it to qualify as a "configuration" file; better to move the last few
configurable pieces out to somewhere else so that upgrading is less painful.)

(Surely I'm not the only person who runs dhclient to get an IP address, but
wants to run my own nameserver?)
