Agreed, I meant in *addition* to pre-deployment testing - say if testing
didn't pick up all bugs and you discover fatal problems post deployment.
How about a postrm::downgrade hook to reverse any changes made in the

I'm aware you can downgrade packages with
`apt-get --force-yes install package=version-revision`
but this doesn't seem to apply any postrm processing on the existing
version of the package being replaced.

I'm using a custom package pool for deploying software, but we need to
