Yeah, I know that the Cederqvist mentions difficulties with SMB-shared
repositories.  (Personally, I think the issues with permissions would be
enough reason to stay clear of that.)

I should probably have been clearer---our repository is currently on a
disk that we mount via NFS.  What are the issues involved with that
specific situation?

(Oddly enough, in the ~18 months we've been using such a system, I haven't
noticed any problems.  There have been stories of CVS causing problems and
losing people's changes, but I always though those were operator error.)

Thanks,

Richard
