Sorry, I was also thinking of workstations run from a CD-ROM
and a ramdisk, and other situations like that.

Any software that adheres to Debian policy (e.g., 11.7.4) won't
break if /etc/resolv.conf is replaced by a symlink.

Recall, too, that we are talking about an optional package here.
An admin with unfixable ill behaved software can simply remove
the optional package.

If you are saying that no change may be made to the Debian
system that could possibly break some conceivable third party
program, no matter how ill behaved, then you are saying that
no change can be made to the Debian system, period.
