Reading through this bug report, it seems to me like this would be a good case for a debconf message of type error. It was added for exactly this sort of case, where something broke during installation that needs the attention of the system administrator, but which isn't sufficiently bad to leave the package in an uninstalled state.
The shell handling is a bit complicated, and I don't have time to work on this myself at the moment, but at least this will capture it in the bug trail for anyone else who has time to work on it. -- Russ Allbery ([EMAIL PROTECTED]) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
