Ah, should be that.  An ordering problem re. cyrus21-common.

Yes.  Nasty little bug, that.

It also Conflicts: cyrus21-common.  It *really* should have caused
cyrus21-common to disappear, and it didn't.

This will require some testing upgrading paths using "piuparts" and chroots
to fix, I fear.

It might be easier to just document it in the BTS (can't happen in
Lenny->Squeeze transitions, since Cyrus 2.1 is not in Lenny), and for the
future, have the initscript heal missing statoverrides.

But we do have to check if it cannot happen also when going from 2.2 to 2.3
or 2.4.  My guess is that it does.
