It gives an error message when you try. You then need to interpret the
error message, retry, and it gives you another error message. You do
this three times, and end up with the command line
cvs2svn -q --fs-type=fsfs --encoding=latin1
-s py.svn.new python

I posted the wrong URL. The right one is
It has distutils right in

I had hoped that it would consume less disk space - but I really should
try with bdb again.
In our operational repositories, I have now migrated everything to
fsfs because it is so much more friendly to backups. You can backup
the on-disk state, and trust that is consistent. With bdb, you need
to use hot-backup.py or some such, and this gives you an entire copy
which then goes into all incremental backups. With fsfs, the incremental
backups really pickup new commits only. (for the Python svn, it doesn't
matter much, since that is excluded from backup, anyway)

So do I. However, I now believe that it is unlikely that SF will provide
automatic conversion (or the automatic conversion will be useless/fail);
instead, we likely need to provide our hand-tuned conversion.
I'll keep collecting issues/complaints about this specific conversion,
and try to integrate them if I can.
