        Here is my repository setup
        $ ls -l /home
        drwxrwxr-x   5 root     root         4096 Apr  4 17:04 cvs/
        $ ls -l /home/cvs
        drwxrwxr-x   2 root     root         4096 Apr  9 20:45 CVSROOT/
        drwxr-xr-x   2 krz      krz          4096 Apr  9 20:02 project1/
        drwxr-xr-x   6 krz      krz          4096 Apr  9 22:30 project2/

        I (user krz) own the project1 and project2 directories, but root
        owns /home/cvs.  Everything works great, except remote repostiory
        commands.  When using a remote repository, the "cvs server" process
        creates a /tmp/cvs-serv{pid} directory, then starts populating that
        directory with the CVS admin directory ("CVS") and other
        sub-directories of the project.  Then in "server.c" line 417, it
        looks for a file "/tmp/cvs-serv{pid}/{subdirectory}/CVS/Repository"
        and if that is not a file, it tries to create
        "/home/CVS/CVSROOT/EmptyDir" which my user (krz) does not have
        permission to create.  Therefore, nothing works :)
        The description contains the information needed to test/repeat this.

        I could work around this problem by giving my user (krz) permissions
        to create directories inside of /home/cvs/CVSROOT.  Instead, I made
        a small patch to have it create the EmpryDir at:
        "/tmp/cvs-serv{pid}/{subdirectory}/CVS/EmptyDir" which seems to work
        for me.
