I do. I'm probably somewhat ahead of you, as shown by the dpkg -l output at the below. Most Debian sources compile cleanly, some need a little bit of hacking, but it's mostly configure or libtool doing the wrong thing. Occasionally, there's a case like ncurses that does an #ifdef __FreeBSD__ that's bogus with glibc.
The problem I'm having is that I can't get freebsd sources to build on top of glibc. The library and utility sources that I need seem to be wanting a lot of stuff that simply isn't in the glibc headers. So I had the bright idea of compiling the freebsd-buildutils package (contains BSD make, install, find, and almost everything else the freebsd sources require) statically against libc. The problem I ran into next was that mtree and install try to look up usernames, and bound against libc instead of glibc, they were looking for a pwd.db that wasn't there.
So I'm faced with a dilemma. Do I: 1. hack FreeBSD sources to build with glibc 2. hack glibc to build FreeBSD sources 3. try to make both libc's coexist
Some combination of option 1 and 2 seems most likely to work. I think we're going to need to be able to use libraries like libkvm with glibc.
I'd been thinking of writing a python wrapper for libcam, and at least cdrecord will want libcam also.
What concerns me most is that any changes I make to FreeBSD sources to get them working with glibc will probably not be acceptable upstream, which poses a large maintenance problem.
