cvs2svn/cvs2git does indeed mostly seem to work with CVSNT repositories,
but it depends on the CVSNT version of the "cvs" command for extracting
the file contents from the *,v files. So if the CVSNT version of the
command no longer supports reading files from the local filesystem, that
command won't work.

cvs2svn/cvs2git does have internal code that knows how to reconstruct
the file contents without any external dependencies (--use-internal-co).
But this code doesn't know about CVSNT's "-kB" binary format, nor any
other new formats that CVSNT might have invented.

So for the moment cvs2svn/cvs2git is dependent on having a CVSNT
installation available for reading file contents.

Ugh it's on my very long backlog. It sounds like you are familiar with
CVSNT, so if you want to get involved, it would be helpful to get your
opinion on the patches or even test them and see how they work for you.
They are available from my Git repo [1] as branches with names
refs/heads/sags/*.

But unfortunately those changes don't help eliminate the dependency on
CVSNT's "cvs" command.
