apt-get dist-upgrade but hold libc6 at 2.3.1-8

[Dan Jacobson <jidanni@dman.ddts.net>]

Gentlemen, junior user me is planning to upgrade sid, but I must stay
away from the fabled libc6 2.3.1-9 so I

# cat $PWD/preferences
Package: libc6
Pin: version 2.3.1-8
Pin-Priority: 1001
# apt-get -o Dir::Etc::Preferences=$PWD/preferences \
  -s dist-upgrade|grep upgraded
297 packages upgraded, 23 newly installed, 87 to remove and 326  not upgraded.
# apt-get -s dist-upgrade|grep upgraded
686 packages upgraded, 60 newly installed, 3 to remove and 4  not upgraded.

I.e. I am going to miss lots with that pin.
It must be that when I do an update, the lists that come back dont
carry anything earlier than 2.3.1-9, leaving a gap:

# apt-cache policy  libc6

  libc6-pic,libc6 2.3.1-9
  libc6-dev,libc6 2.3.1-9
  libc6-dbg,libc6 2.3.1-9...

and doing those in preferences too doesn't help.
It must be that I need libc6 2.3.1-8 etc. in my package lists and a
simple apt-get update doesn't do that....
