Hi all,
it seems that just reading the policy again sometimes solves a problem...

I was under the impression that "new-prerm failed-upgrade" was called
only to clean up after the failing old prerm script. But rereading 6.5,
I understand that the new prerm is called as a replacement for the
failed old prerm, and if it succeeds, the upgrade can proceed without
problems. Am I right?
