The differences between both ABIs aren't that big anymore since the switch to libio. We don't have all the old symbols however, but that's only a problem if you want to run old binaries. We already talked about making both ABIs compatible but that isn't possible yet at the moment. If they are compatible a big part of the archive can be shared. We already have talked about linux emulation, but we don't want it as we see no need for it. We don't want to be able to run LSB packages either. The only thing we would care about is Debian and if we can reduce the load of the ftp server we will be happy to do so.

Both GNU and BSD have a filesystem layout which are pretty compatible AFAIK. Only GNU/Linux wants to differ for some reason still unknown for me. > > I think Hurd people are getting a rough ride, but their strugle is making > > debian better, i applaud their stamina. > > They would get a lot less flack if they tried to start these threads just > after the woody release, when people will be in a mood to listen to big > changes. If I'm right woody isn't in freeze for 3 years.

I don't know about the Hurd. It's a bit hairy but not totally impossible. The libc ABI has to be same for this however. Because the BSDs don't use glibc, we probably have about 2 systems. It actually does make sense, because when you look at the overall picture, there exist actually two free systems, BSD and GNU, which both have their variants. If somebody ports glibc to *BSD, it would be possible to also have compatiblity between that. If I'm right glibc used to run on 4.3BSD, so that's not entirely impossible.
