In order to get a bootable CD for the Hurd here's the recipe I
followed, your's will be similar. I needed a grub-0.92 with a patch
from...
http://alpha.polynum.org/misc/
...and I needed the version 1.16 of mkbimage (I don't exactly remember
where I got that from). You can grab a copy of...
http://sleepingsquirrel.org/hurd/hurdcd.iso.gz
...which is a bootable *.iso with the copy of the patched grub and the
version of mkbimage I used. Here's the recipe I followed (under linux).
mkdir ./2.88floppy
mkdir ./isodir
cp grub/* 2.88floppy/boot/grub/
cp grub/* isodir/boot/grub/
cd 2.88floppy
tar -cf ../floppyimg.tar *
cd ..
mkbimage -f floppyimg.tar -t 2.88
cp 2.88.image isodir/
mkisofs -r -b 2.88.image -c boot.catalog -o hurdcd.iso isodir/
cdrecord -v speed=4 dev=0,0,0 -data hurdcd.iso
...That was the recipe for using a floppy image. If you use the "-t hd"
switch of mkbimage, you'll get an ext2fs El-Torito HD emulation image that
can be any size (I've got one here 300+ MB). You then can use "root
(hd0,0)" in grub to boot something. Also, invoking mkbimage with no
parameters will give you some additional help messages. You might also
want to check out this thread for any help context information (this is
where I was having problems)...
