After latest upgrade installation of lilo fails.

I am not using raid and have the entry boot=/dev/hda in lilo.conf as
specified in the man page. The installation fails with error code 01
which according to the lilo man page means invalid disk command.

Does it now want a UUID? If so, where do I find the correct UUID.
Values for the partitions are listed in /etc/fstab but not for the MBR.
I have checked several posibilities in /proc without success. In
particular in /proc/bus there are now only three subdirectories, Input,
pci and usb.

Since this a new problem I checked the archives for August and September
but found nothing about lilo.

Your post is lacking important information to diagnose the problem.
For example,

(1) Are you running Lenny or Squeeze? (or something else)
Squeeze
(2) What architecture? (i386 or amd64)
amd64
(3) What kernel are you running? Is it stock or custom? If it is
custom, exactly how did you build it?
Stock kernel 2.6.32-5-amd64
(4) What additional backup kernels (if any) do you have installed?
/boot/vmlinuz-2.6.24-1-amd64.sav
/boot/vmlinuz-2.6.26-1-amd64
/boot/vmlinuz-2.6.26-2-amd64
/boot/vmlinuz-2.6.30-1-amd64
/boot/vmlinuz-2.6.30-2-amd64
/boot/vmlinuz-2.6.32-3-amd64
/boot/vmlinuz-2.6.32-5-amd64
(5) What files, if any, are present in the following directories:
/etc/kernel/postinst.d
initramfs-tools
pm-utils
zz-lilo

Note: I have grub2 boot loaders in the MBR's of the two sata hard drives
which I knew as sda and sdb and lilo on the MBR of the ata drive which I
knew as hda. The grub2 installation recommended putting the loader in
all MBR's but problem with linux-base made it impossible to boot with
grub. The lilo boot still worked and the linux-base problem was
resolved when all references to the cdrom and usb drives was removed
from fstab. The 2.6.32-5-amd64 kernel is apparently too large for lilo.

First of all, thank you for taking the time to collect and post all of this
information. I know it must have been a pain; but believe me, there's no way
to solve the problem without this information. At the risk of telling you
what you already know, allow me to explain what happened. Prior to kernel
2.6.32-5, the traditional IDE drivers were used for traditional IDE hard
drives (also know as parallel ATA or PATA drives). The user-space device
names for these drives were called /dev/hda, /dev/hdb, etc. On the kernel
side, these devices used major number 03. Serial ATA
(or SATA) drives were treated as SCSI disks and used the SCSI naming
convention. On the user-space side they were called /dev/sda, /dev/sdb,
etc. On the kernel side, these devices used major number 08.

Starting with kernel 2.6.32-5, a newer driver was used for PATA drives
which, like the SATA drives, treated them as SCSI disks. In a typical
PC with only one hard disk, the device name simply changed from
/dev/hda to /dev/sda. However, in your case, since you already had two
other disks which were already being treated as SCSI disks, you now
have all three disks being treated as SCSI disks. The question is,
which disk is which? I.e. is the old /dev/hda now /dev/sda? Or is
it now /dev/sdb or /dev/sdc?

If I am to believe the comments in /etc/fstab, you used to have a
partition called /dev/hda1, mounted as /temp, which has a UUID of
4a2915d8-60cf-498e-a15c-f0bc6ebdb25e. According to the output of
"ls -Ald /dev/disk/by-uuid/", this uuid is now associated with
/dev/sdb1. You also used to have a partition called /dev/hda5,
mounted as /storage, which has a UUID of
408287f4-8b15-42d1-b6d3-bfeaefde3002. According to the output of
"ls -Ald /dev/disk/by-uuid/", this uuid is now associated with
/dev/sdb5. Thus, we conclude that what used to be called /dev/hda
is now called /dev/sdb. The "quick fix" would be to code

boot=/dev/sdb

in /etc/lilo.conf and re-run lilo. And that will work, as long as
you are running a kernel which uses the newer libata drivers.
But if you ever run lilo while running a kernel which uses the older
IDE drivers, this will fail. That's not good. What you want to
do is to use a udev-created alias what will map to /dev/hda when
running a kernel which uses the old IDE driver and which maps to
/dev/sdb when running a kernel which uses the new libata driver.
And we can do that. Based on the output of "ls -Ald /dev/disk/by-id/",
what we really want to use is

boot=/dev/disk/by-id/ata-WDC_WD307AA-00BAA0_WD-WMA2F3071727

This will work with both types of kernels. linux-base apparently
isn't smart enough to make this substitution. But that's what you
should do.

However, since I'm up to my ears in your system configuration,
I would like to make some recommendations, if I may.

(1) Avoid having multiple boot loaders installed at the same time,
if possible. If you can, find one boot loader which can boot
everything and stick with it.

(2) If you ever create a custom kernel, you will have problems
with lilo because a kernel created by the Squeeze version of
"make-kpkg" or by "make deb-pkg" does not maintain the symlinks.
("do_symlinks = yes" only works for custom kernels under Squeeze.)
For a more general treatment of this topic I recommend that you
read http://www.wowway.com/~zlinuxman/Kernel.htm, especially
"Step 10: Customize the Kernel Installation Process". You will
need to install hook scripts to maintain symlinks in this case,
such as the ones referenced on the web page.

(3) If you are using lilo on an amd64 system, you might want to
try the latest upstream version of lilo. The Debian package is
available here:

http://www.joonet.de/lilo/debian/squeeze/lilo_23.0-1_amd64.deb

Although this is in Debian package format, this package is not
supported by Debian at this time; so if you have problems with it,
please do not open a Debian bug report against the lilo package. But
I do know that the upstream author, Joachim Wiedorn, made a number
of changes to lilo to work better with the amd64 architecture,
and he uses it himself.

There is one known bug in the package, but it is easily fixed.
Change "#!/bin/sh" to "#!/bin/bash" in
/etc/initramfs/post-update.d/lilo.
