No concurrent versioning system with a shared repository, and
particularly not one that can operate in a client/server mode, can ever
possibly make any use of ownership, nor even of most permissions bits.
Ownership information, and most permissions bits, "MUST" always be
specific to the client and it MUST NOT be dictated by the repository.

CVS does already partly handles the one permission bit that's meaninful
to copy from the repository, for what it's worth (almost nothing in

If people would learn two things then all this stupidity would disappear
in a puff of smke:  (1) CVS is a text file content change tracking tool, and
_only_ a text file content version tracking tool; (2) all these things
(file permissions, ownerships, symbolic and hard links, etc.) can far
FAR more elegantly, simply, and clearly be managed by a build script,
the source for which can be stored in CVS.

How do you expect to meaninfully combine a tool that creates binary
files with CVS?!?!?!?

Have you not been paying any attention to the rationales I and others
have given for why CVS is the way it is and why it doesn't do some
