That's ^^ what I meant by compromising. Your comment above just answered my question: "Once your repository is used with CVSNT there is no going back to CVS". Naturally, I'll do a test migration first but somewhere or so many months down the line, should we become wishywashy and decide to switch back to CVS, there will be no going back nor do I see any tools or utilities out there for converting cvsnt repo to a cvs repo. > > You should be aware that CVSNT is much more secure than CVS and in > particular: > * the 'repository path' used in the $CVSROOT does not need to be the > same as the physical path (configure in /etc/cvsnt/PServer) > * the permissions/mode of checked out files does not need to match the > permissions/mode of the RCS files in the repostiory > * CVSNT has it's own ACL's > * CVSNT can run in a chroot jail > * etc Yes, the items you listed and many more features, are tantalizing enough for us to consider switching. > > > 2-Does anything special need to be done to the repository or > > are both flavors of CVS able to read the repository > > universally w/o any additional formatting or tweaking? > > The simple answer is: CVS cannot read a CVSNT repostiory.
