Unclear...caching nameds are a big performance win, and keeping

In general, resolv.conf clobbering should REALLY be easier to turn off.

Other options:
* Have athena-bind install a /sbin/ifup-local which restores
inetd.conf (or a demon which sticks its PID in
/var/run/netreport and restores the file upon receiving
SIGIO -- but that would be more work.)
* Have athena-bind's init script restore inetd.conf.
(Doesn't help in the PCMCIA case. :-/)
* Make resolv.conf immutable with chattr +i.
