While that's the most talked about scenario nowadays, I've found these
(unsigned) checksums extremely useful for proving that a problem
installing NetBSD was in fact down to data corruption.
The person doing the installation didn't believe me that there was a
problem with the ISO image until I had him actually verify the checksum.
So I'd say, even without digital signatures, checksum files *are* useful.
