Andrew,
In the section where you are adjusting drive references, you will want to
leave /dev/hdc and /dev/hdd drive references alone. You are only messing
with the first ide channel, not the second one. They will NOT change. The
only exception to this is if you plan on re-jumper'ing and re-cabling ALL
of your drives.
For the part of writing the MBR to your new /dev/hda I would recommend that
you just boot up with your "rescue" disk or cd after moving the disks and
jumpers then mount your new /dev/hda? root file system and chroot to it and
run lilo then. Just follow the normally expected "rescue" procedures and
it should work just fine. This is how I have done it many times when
changing out drives.
Good luck,
Loren

Greetings-
I have a machine currently running potato. It has four IDE drives in
it. /dev/hda does nothing important; it's an old (probably 1993 or
1994) 1.2G whose sole role in life at this point is to have an MBR with
LILO to boot DOS, NT, or (99% of the time) Debian.
That drive is quickly dying, and when it dies it brings down the IDE bus
and therefore the system. So I need to get rid of it. I'd like to upgrade
to woody at the same time. Here's my plan; any comments or advice are
welcome.
1.) Back up /etc to somewhere safe
2.) Edit /etc/fstab:
change all references to /dev/hdb* to /dev/hda*
remove references to (unused) filesystems on what is now /dev/hda
change references to /dev/hdc* to /dev/hdb*
change references to /dev/hdd* to /dev/hdc*
(cdrom and zip drive are SCSI so not relevant to this process)
3.) Edit /etc/lilo.conf to point linux to /dev/hda instead of /dev/hdb
4.) Write /etc/lilo.conf to the MBR of the current /dev/hdb (about to
become /dev/hda). THIS IS THE STEP I DON'T KNOW HOW TO DO.
5.) Power down
6.) Remove current /dev/hda
7.) Rejumper current /dev/hdb as master
8.) Power back up
---At this point I *hope* to have the old system (potato) up and running
without the dead disk.---
9.) edit /etc/apt/sources.list to point to testing instead of stable
(should I use woody instead of testing?)
10.) apt-get update
11.) apt-get install apt apt-utils
12.) apt-get dist-upgrade
What, if anything, am I missing, or should I be worried about?
Thanks.
