I hope this is the final version for a while. The script works here on a
freshly installed bo.
Watch out for line folding.

# 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
#
# TODO: (probably by somebody else. this script is mostly good enough imo)
# - error checking
# first, build up a list of installed -dev packages so that we can
# remove them. remove wg-15-locale too.
#
# this is necessary even on machines which aren't doing libc6
# development because libc5 can't be upgraded to latest version without
# removal of libc5-dev which also necessitates removal of other -dev
# packages like libdb1-dev and libdl1-dev if they are installed.

grep -v deinstall |

# now install the new versions of things. Just the bare minimum to let
# the user safely run dselect for the rest of the upgrade.
# change this to prompt the user for the location of the debian archive.

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.
Finally, remember to fix up wtmp and utmp, otherwise last and
who and sac etc wont work. here's what Miquel van Smoorenburg
[EMAIL PROTECTED] 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
