When I install using the TUI and afterwards run setup to configure X, I get this: There is something wrong with the file /usr/X11R6/lib/X11/XF86Config This file should normally be a link to /etc/X11/XF86Config It asks me if I want to make the link. The file isn't there to start with. Perhaps it ought to just make the link if there's not one there already.
This is fixed as of XFree86-4.0-0.31 or so.
