I think in this case it would have to be something within the postinst checking to see if it were the last module and thus needed to restart the server... I don't think the intent was for DebConf to be able to make this assumption but rather to facilitate a mechanism for the postinst scripts to be able to talk to one another so they don't all have to duplicate the same step of restarting... Respectfully, Jeremy T. Bouse Joey Hess was said to been seen saying: > I don't see how a shared template can prevent apache from being > restarted N times. It can cut down the number of times the question is > asked to once per upgrade, perhaps, but each postinst will still need to > independantly Do The Right (idempotent, etc) Thing, and a postinst has > no way of telling if it is the last of the N postinsts, and should thus > restart apache, or not. > > Likewise, while there is a way to make a shared question is asked > whenever a new package that uses it is installed and/or removed (there's > an example of this in the debconf docs), I can't think of a good way to > make a shared question be asked exactly once when any number of packages > that use it are upgraded together.
