Hi Greg,

You obviously have very strong feelings about this...  Can
you help me understand specifically what risks are involved?

These are the precautions I'm taking:

 - The CVSROOT directory is read-only, so customers can't add
   their own users without going through me, nor can they
   set up wrappers.

 - CVS runs as the user(s) specified in the CVSROOT/passwd
   file. Each repository gets its own user, that does not
   have access to any other repository.

 - The cient-server traffic is protected with SSL.

 - I am in the process of setting up a chrooted jail
   (or jails) on the server, to keep CVS from accessing
   any other directories.

What am I missing? What other sorts of security issues do
you see?
