I'm actually all for getting the upstream i.e. cron/PAM acting more sane 
so we don't even arrive at the "logging huge amounts of 
low-effectiveness information" problem, but as you wrote in your other 
reply, that might be a whole separate project.

In the meantime mgilbert's suggestion for using loginctl --linger 
parameter seems to accomplish the goal of quieting cron logging. Any 
side effects to consider?
