Installing Hurd on Bochs


Many others have reported installing the GNU on the Bochs so I thought
I could try it out without disturbing my "work" (which still seems to
depend on the other GNU OS). Some random notes.

1. Marcus' gnu-latest.tar.gz does not have its grub files under /boot/grub
   and does not have have a menu.lst containing the boot lines. This
   would certainly simplify the boot procedure as the floppy boot
   would only be required to do "root (hd0,0)" and "setup (hd0)".
   Or perhaps the hurd-installation guide could suggest that the
   unpacking of the tar.gz. be followed by
	     cd /gnu/boot
	     mkdir grub
	     cd grub
	     ln -s ../../lib/grub/i386-unknown/* .
	     cat <<EOF > menu.lst 
	     <paste relevant lines here>

2. Marcus' "cross-install" script is a bit out-of-date. The crude script
   enclosed makes use of grep-dctrl to generate a newer list of
   "essential" packages.

3. The second run of "native-install" runs into difficulties if run
   with an image created with "cross-install" because
   "adduser" version 3.49 seems to be broken on Debian GNU---is this
   because of perl?

many it's research.
