Dear folks
I'm trying to change the bootloader of the harddisk installation of knoppix 3.6 on a compaq presario laptop from LILO to GRUB.
The following is the entry from lilo.conf:

image=/boot/vmlinuz-2.4.27
label="Linux(2.4)-1"
initrd=/boot/initrd.img-2.4.27
append="ramdisk_size=100000 init=/etc/init lang=us apm=power-off nomce q
uiet lang=us"
read-only

I changed this to:
title deb-2.4.27
kernel (hd0,9)/boot/vmlinuz-2.4.27 ramdisk_size=100000 init=/etc/init lang=us ap
m=power-off nomce quiet lang=us
initrd (hd0,9)/boot/initrd.img-2.4.27

for GRUB in /boot/grub/menu.lst.
But I get the following error message during boot:
(mount: fs type devfs not supported by kernel
umount: devfs: not mounted)
pivot-root: No such file or directory
/sbin/init: 426: cannot open dev/console: No such file
kernel panic: Attempted to kill init!

I've noticed an open bug reported:

23. Hardware Dell Optiplex 260. Installed Knoppix 3.6 to hard drive. hda1: NTFS, hda2 FAT32, hda3 linux, hda4 linux swap. At the beginning of the bootup process I get the following error message twice: (Norm)

initrd-tools 0.1.73
mount: fs type devfs not supported by kernel
umount: devfs: not mounted

But the point is I have been already able to boot by LILO as the secondary bootloader!

What am I missing?
Thanks in advance.
