Yes, or pass a parameter with "first" and "second" or something. But the
migration is then harder as *all* scripts need to know about it before it
works...

Sure, this is ideal. Many postinst-scripts already do this. Great, as I
comment on in another message. But the main point is that my idea is
completely transparent to the existing system: we file bugs, they get
fixed, the system gets better and better.

Certainly. But too complicated to be *required* RSN.

I think dpkg still needs to know that a package can be "half-configured",
if I understand you.
