Corrected Cheap*bytes autoup.sh script
Upon request, here's the updated script sent to me by Cheap*Bytes:
[For anyone reading this in the archives:
The original Official 2.0 CD-Rom distributed by Cheap*Bytes contained the
cd_autoup.sh file included by Debian with the distribution. The script
was broken at the time the dist. was set--several libraries were not in
locations the script expected. This updated script now properly locates
the needed libraries to do an out-of-the-box upgrade. In addition, the
original cd_autoup.sh required the user to cd several layers down into the
CD before executing the script. The modified script does not have this
requirment and merely requests the location of the cdrom's mount point.]
#! /bin/sh
# upgrade a libc5 (bo) machine to libc6 (hamm).
# The cd version of this script is designed to run from from a top level
# directory of the Official Debian 2.0 CD without any input from the user
# execept as required by dpkg installation scripts.

I have tried to remove any packages that would be broken by the
upgrade, but I may have missed some. Some "Errors were encountered
while processing:" messages were displayed earlier; they were
harmless. If any such messages are visible now, make a note of the
package names, since they must be removed or replaced with their
equivalent from hamm.

libc6 is now installed. Now run dselect to upgrade the rest of your
system. It is recommended that you run the access, update, install,
and configure modules of dselect initially to just upgrade all
installed packages. After that you may use the select and install
modules to install additional packages if necessary.
Keep in mind that when dpkg/dselect upgrades many packages (and almost
every package on your system will be upgraded in this step), it is
usually necessary to repeat the install and configure steps several
times (perhaps four or five times) before the whole system is
configured. The apt access method for dselect improves this
considerably.
If you have apt installed (see discussion under "Upgrading using
apt"), the apt access method should be selected in dselect's Access
module. Apt is much faster than any of the older dselect access
methods. When that's done, reboot with "shutdown -r now" for the
utmp/wtmp wrapper functions in the upgraded libc5 to take effect.
All development packages (-dev, -dbg, and -pic) and a number of other
incompatible packages have been removed during this upgrade procedure
due to conflicts between libc5 and libc6 versions. A list of the
removed packages are in the file "/root/removed-<today's date>". You
will have to install the libc6 equivalents of any of these packages
that you need. If you will be doing any libc5 development work, you
will also want to re-install (from the old-libs directory) any of these
libc5 packages you need.
Finally, remember to fix up wtmp and utmp, otherwise last and
who and sac, etc. won't work. Here's what Miquel van Smoorenburg
<miquels@cistron.nl> had to say about this recently in debian-user
mailing list:
> 1. You need to update ALL your packages to hamm
> 2. Reboot if you haven't done that already
> 3. You need to move the wtmp file and truncate the utmp file:
> cd /var/log
> mv wtmp wtmp.libc5
> touch wtmp
> cd /var/run
> cp /dev/null utmp
> 4. You might want to reboot again to make sure
>
> This is because the "struct utmp" and thus the utmp and wtmp
> "databases" are different between libc5 and libc6
You now have a Debian Gnu/Linux v2.0 system. Have fun!
