libc6 2.3.x is only available from "unstable" debian pool.

Having just learned how to set up a "hybrid" release, I don't want
to reccomend this to anyone.  IMHO, this is for someone willing to
take risks with stability of a system, is not a developer, and wants
something that's only in "unstable".  Drawback with "hybrid" is package
maintainers will not like you if you report bugs - mixed releases are a
PITA to reproduce. Personally, I'm not going to report bugs
with the one box (my laptop) I have setup this way.

The following seems like the "least evil" way to go about it:

1) /etc/apt/apt.conf should have the line:
	APT::Default-Release "testing";

2) duplicate "testing" entries in /etc/apt/sources.list for
   "unstable" as well. run "apt-get update".

3) copy the following 7 lines into /etc/apt/preferences:
Package: *
Pin: release a=testing
Pin-Priority: 650

Package: *
Pin: release a=unstable
Pin-Priority: 90

  This allows one to install from unstable but not update such debs
  *until* they get promoted to "testing" release. Once this deb version
  is promoted to testing, it tracks versions like normal.

  Read "man apt_preferences" for more details.

4) "apt-get install libc6/unstable" to update to libc6 2.3.1 lib.
   You will have to install several other packages from /unstable
   at the same time. But apt-get will complain about which packages.

hth,
