"@stop" (when cron is stopped) is easy to implement, but the use cases=20= =20 for=20this are ... IMO very limited (and I would question if another way=20= =20 of=20implementing the application logic where this is used may be better). "@shutdown" is not only a simple change to cron but also needs some=20=20 logic=20to distinguish a stop/restart of crond from a full system=20=20 shutdown.=20As such from a layering logic I would rather go with a rc=20=20 script=20instead of a cron entry. I understand that real-world ... "rules" ... can lead to situations=20=20 where=20@shutdown would make life more easy. How far do we want to go=20=20 there?=20Where do we draw a line between layering violations and stupid=20= =20 policies=20or convenience or "I don't want to talk with a colleague"=20=20 situations=20(or whatever it is)? This message is not a "no-vote", it is a "take a step back, take a=20=20 deep=20breath, and ask yourself if we really want to do that".
