In the past, it has been suggested that there be a 'make rmobs' target
or something similar.  I'd strongly oppose a non-turn-off-able doing
this as part of installworld.  That's too dangerous.  I've
experimented with some automatically delete obsolete files schemes in
the past, and there is *MUCH* potential for foot shooting and ***
******* to make it be on by default.

NetBSD's approach in etcupdate is based on a master list of files that
have gone away.
