cvsup2.kr.freebsd.org is running on a Debian 4.0 amd64 system, and
cvsupd is really a huge pain for us.  We are using some ancient
cvsup/cvsupd i386 .deb packages with old i386 C, M3, and X libraries
installed separately.  Those cvsup packages even disapeared from Debian
experimental, perhaps a few years ago.  I haven't tried CM3 or other
compilers instead of ezm3 yet, but neither are they available on Debian.
CVSup seems to have no future, so putting any effort into it seemed
pointless.

If csup is popular and reliable enough, shouldn't we migrate our
infrastructure upon it?  Since it's written in C, csup is much more
portable and transparent to changes of OS.  FreeBSD mirrors running on
non-FreeBSD platforms (like ours) or running on IPv6-only nets will be
relieved from pains of dirty hacks.  I'm not confident enough, but rsync
could be another viable solution.  (Please forgive my short knowledge if
similar effort is already going on.  I'm not actively using FreeBSD any
more these days.)

I just can't understand why the leading operating system for networking
is still relying its update system on such a handicap'ed tool.
