Since info-minix is up gaian, here's the fix to the chroot(2) problem reported
earlier. Quite simple, isn't it? :-)
Of course, there's a hack to it :-) (when generating the cdif, i forgot an
earlier patch); add #include <minix/boot.h> in the list of include files,
otherwise ROOT_DEV remains undefined.
