Once upon a time I implemented some code to add a default_hostname
variable to rc.conf which was then used by the startup scripts and
dhclient-script to allow the local network to override the name if
desired while insuring that the system had a name at all times (required
for laptop use).  I'd take patches to do this.

P.S. hacking this into rc.local won't work longterm because addresses
will be assigned in a totally different context.
