Re:libc5 to libc6 auto-upgrade script
This version should be close to good enough. The major change since the last one that was posted is the ability to upgrade from files in the current dir instead of a local mirror requirement.
This script still needs testing.

# upgrade a libc5 (bo) machine to libc6 (hamm).

# Revision History:
# v0.0: 1998-01-08 (morning)
# - a rough transcript of scott's doc and my own experiences
# v0.1: 1998-01-08 (night)
# - a few bugfixes
# - i got unlazy and put in the right subdirectories for each package.
# should run a lot faster.
# - now checks for failure at critical points and exits with a different
# exit code for each failure.
# - now uses 'binary-$(dpkg --print-installation-architecture)' instead
# of 'binary-i386'.
# v0.2: 1998-01-09
# - fixed the perl-base/perl install (thanks Lindsay!)
# - improved the DEVPACKAGES=$(dpkg --get-selections...) and added -dbg
# packages.
# v0.3: 1998-01-09 (p.m.)
# - fixed some directories
# - changed "-iB" to "-iBE" so that if the script fails and is run again
# it will not disturb things already in place.
# - added a final "dpkg --configure --pending".
# - sanity check that we are in the right place added
# v0.4: 1998-01-10 (Igor Grobman)
# -made it possible to place all packages in current dir.
# -added -pic packages to removal list.
# -make sure dpkg-dev does not get selected for removal.
# -moved dpkg-ftp and dpkg-mounted to the end.
#v0.5: 1998-01-10 (Igor Grobman)
# -added a note about upgrading libraries
#
#
# TODO: (probably by somebody else. this script is mostly good enough imo)
# - error checking

libc6 is now installed. Now run dselect to upgrade the rest of your
system. When that's done, reboot with "shutdown -r now" for the
utmp/wtmp wrapper functions in the upgraded libc5 to take effect.
BTW, if you aren't using it already, check out dselect's "mountable"
access method. It's much faster than the standard "mounted" method, and
it logs everything that happens in /var/log/dpkg-mountable. You'll want
to set "Allow overwriting repeated files?" to yes, and for extra speed
set "Enable MD5 checksumming?" to no.
If you are installing manually using dpkg, remember that all libc6 (g)
libraries conflict with all the versions of their libc5 (non-g)
counterparts prior to a certain version which placed libc5 libs in
/usr/lib/libc5-compat. This means that they conflict with your bo versions
of libc5-linked libraries, but not the hamm versions. For example, if you are
installing xlib6g, you should install xlib6 from hamm first before installing
xlib6g unless you have nothing that depend on xlib6 in which case you can safelyremove it.
Finally, remember to fix up wtmp and utmp, otherwise last and
who and sac etc wont 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
