If, on a "unstable" system, Apt sources for "testing" are also listed in /etc/apt/sources.list, you can always do a `apt-get -t testing install libc6` or `apt-get install libc6/testing`. Or, you could create a file /etc/apt/preferences and pin the "testing" version of the package with a high enough priority. See `man apt_preferences`. Then do a `apt-get dist-upgrade`. > The only interface for rolling back is switching the entire machine to > an earlier distribution and telling apt to try to downgrade -- which is > unlikely to work.

This is probably one of the worst ways of rolling back few or even a single package.
