I found the following statement (by Mike Stone) near the bottom of http://bugs.debian.org/cgi-bin/bugreport.cgi?archive=no&bug=25882:

No files should have group "nogroup". Likewise, no files should be owned by "nobody". If either of these is the case somewhere on your system you should create (a) new user or group for that purpose...

I assume he and the other people on the list know what they are talking about, are right about this, and there is a good reason for this -- I assume it is related to security. But, I have no understanding of why this should be so. And, IIRC, during a TWiki install, if the apache user is nobody we are supposed to make the files owned by nobody. (But, I may be very wrong about that -- will check next time I do an install.)

And, is it only applicable to Debian or does it apply to any Linux distribution?

Anyway, I put this here so I would occasionally stumble across it and think about it, and maybe someday will understand it. (It does sound sort of intuitive in a sense, if there is a user named nobody, it makes sense that, as a nonentity, he should own nothing -- but ??). (Or somebody else will stumble across this and give me some insight (on this page).)
