If you change the passwd/group files before running the find, this
wouldn't be a problem. It could cause some havoc if mail programs (for
example) couldn't access their files for the few minutes it takes to run
the find though. Stopping MTAs before running the find might alleviate
that problem.
Someone else mentioned that running chown will strip the set[ug]id bit.
This didn't happen when I tried it. Is it supposed to?
Is there a good reason why a program would use a uid instead of a uname?
