I had a similar problem, solved by changing how the system looks for
devices to mount.
The issue is differences in disk scan sequence for the BIOS, boot loader
and kernel. In my case, I use Grub, so I can't speak for how exactly to
do this with LILO (or even if it's possible, YMMV).
The following assumes you've booted from a rescue CD of some sort. You
will first need to label your disks (or at least, check that they have
proper labels), and then that you've mounted your hard disk partitions
in an appropriate way so you can access the files you'll need to edit.
The solution is to not use the /dev/disk-dev name for booting and
mounting your disks. During install, Debian will label the devices it
creates with names like '/', '/usr', '/var' and so on, reflecting the
filesystem mount point location (though it does not need to be this way,
it sometimes helps to be able to determine this from the disk itself).
If you've added any disks after the fact, you may need to manually use
the appropriate fs type label command and add one. But, you *will* have
to change the label for the root, because you need a label that will
translate into a valid "file" name in the file system, and '/' is
already in use. I chose to use '/root'. (Note: if this all works, you
can see why this is required by looking in the /dev/disk/by-label
directory, using the -l option.)
You will need to edit .../etc/fstab and the LILO configuration file. In
fstab, change the '/dev/hd-dev' name to 'LABEL=label' where label is the
device's label ('/var', '/root', etc).
Edit the LILO config line for the kernel like this (an example from a
Red Hat EL system, not running LILO but with an anaconda config file for
it):
image=/boot/vmlinuz-2.6.9-5.ELsmp
label=linux
initrd=/boot/initrd-2.6.9-5.ELsmp.img
read-only
append="rhgb quiet root=LABEL=/1"
The important part, to begin with, is in the append line for root=, add
this as appropriate for how you labeled your hard disk root.
Then run lilo to install it and try rebooting your system.
I did have issues, with my grub setup, due to grub itself needing to
know the disk it needed to work with to find the kernel file. The
install of grub used the kernel's idea of the root device (run from the
install environment) but grub, run from the disk MBR, saw something
different. I don't know how you'd determine this for LILO or if it even
needs doing. You'll know if you do, because your system will not boot. :-O
I hope something in this is helpful to you.

Hi
Yesterday I run apt-get install linux-image.2.6.17 (average idea of the
command).
Obviously all dependants etc were satisfied and this morning on
rebooting my machine boot and then fell on a busybox screen.
I wrote the messages down, but I hope someone can help me with this and
this is the second time this has happened. Im upgrading from 2.6.8 and I
run testing on my machine.
Begin moutning root file system
Begin Running /scripts/local-top
Done
Begin Running /scripts/local-premount
Done
mount: mounting /dev/root on /root failed No such device
Begin Running /scripts/local-bottom
Done
Done
Begin running /scripts/init-bottom
mount: mounting /root/dev/ on /dev.static/dev/ failed No such file or
device
mount: mounting /sys on /root/sys failed no such file or device
Target filesystem doesnt have /sbin/init
My question is, when on reinstalling debian and installing 2.6.17 and
this happens again.
My question is, how or what do I edit to force it to work.
If anyone can assit, this would greatfully be appreciated.
Kind Regards
Brent
