I thought long and hard about this issue when I was implementing checkout mode in CVSup. My conclusion, which I still hold, was that checked out files must have their RCS keywords expanded "as if" the checkout had occurred on freefall. That means that the Header keyword must expand to something that starts with "/home/ncvs", no matter where the repository really is. CVSup has a notion of a "canonical" repository directory to support that. I.e., the physical repository may be anywhere, but the paths in $Header$ and $Source$ keywords will be expanded as if the repository were in the canonical location. I think this is important. Can't you make a symlink on your CTM machine "/home/ncvs -> /pub/FreeBSD/FreeBSD-CVS" and set CVSROOT to "/home/ncvs"? That would solve the problem.
