It relies on us coping with a mixture of packages, and not needing
to upgrade them all at once -- so a libc6.deb is first moved across,
followed by packages that depend on it as they become available. It's
still Brian's decision when we've got enough libc6 packages done to
say "Yup, that's good enough. Let's release."

This is a mischaracterisation of how unstable is intended to work.

Since we would have three distributions: stable, prerelease and unstable,
there isn't any longer a need to have every single package in unstable --
the ones that are in operational condition go in prerelease.

Following unstable thus means following prerelease with a bunch of upgrades
from unstable. Packages only remain in unstable long enough to ensure there
aren't any stupid "make-your-system-unusable" bugs.
