Will think about that. However, I would prefer to just tell the user
what he/she would need to do to fix the bug. I will probably pull the
code block from postinst and provide it as a small script in
/usr/share/doc/cyrus-common-2.2 or detail the steps in README.Debian.

Oh well, but _how_ do we make them disappear during upgrades?

Probably yes. But at least this part I was aware of (I mean that the
conffiles are safe during the upgrades).
