See wishlist Bug#114625 that I filed a while ago after doing exactly that on my Hurd install. All the binaries (and libraries!) work, but the package management scripts get confused. Since filing the bug I've looked into the problem a little more closely and found that the trouble lies in the fact that /usr/bin/X11, /usr/include/X11 and /usr/lib/X11 are all symlinks included in the xfree86-base package (they point to ../X11R6/bin, ../X11R6/include/X11, and ../X11R6/lib/X11 respectively). When you move all the files out of /usr/X11R6, you have to delete those symlinks (as the real directories will now go there). I've looked at the posibility of changing that package to create the symlinks in the maintainer scripts, but it seems a bit tricky to get the relative links right (though I'm not a very good shell script hacker). I imagine the change would require checking that the two locations (/usr/FOO/X11 and /usr/X11R6/FOO/X11) refer to the same place (probably using readlink(1) with the -f option which calls realpath(3)), and if not, creating the proper symlink. For your reference, I've attached the xfree86-common.preinst script. The problem lies in the use of the maplink function in the check_symlinks_and_* functions. That would all have to be significantly modified. If no one else gets this fixed, I may work on this a bit more after my finals are out of the way (in three weeks). -- Steven Barker [EMAIL PROTECTED] A penny saved is ridiculous.
