Check out Tobias Roth's profile.

It will allow you to define any number of "profiles" and the first one
that matches our current connection will do a unionfs mount of a MD file
system over /etc. It must contain a new rc.conf and may contain any
other /etc files specific to a given location. I typically have two
start_if files (one for my wireless and another of the wired connection)
and a resolv.conf file in each profile.

It is a bit awkward to set up, but once set up, it just works. If I ever
have the time, I want to write some utilities to simplify setup and
management of profiles.
