On a side issue, there are security reasons to disallow symlinks to areas 
the repository, aren't there?  symlinks that lead outside the repository could 
used as a way around '--allow-root'.  Mount points, I would expect are tough
enough to create that sysadmins can be trusted to track them.  Symlinks seem 
they should be double-checked by CVS, though.

I will admit that the only initial exploit I can think of requires shell access
or write access to CVSROOT, but the latter might be enough to bother some
