9 Amusing that you classify 99.999% of all desktop installs as "big
10 complex installs."

12 But, I agree that it makes far more sense to just have desktop users
13 use an appropriate cron implementation designed to handle the machine
14 being off most of the time vs trying to use shell scripting to make
15 vixie cron into such an implementation.

17 FWIW this is probably the reasoning behind including cron-like
18 functionality in systemd, and having it support optionally running
19 jobs if the system was down during a calendar-based event. It was
20 considered bare-bones functionality that any desktop or generic server
21 would need. It is, of course, optional, and just about any kind of
22 rule is supported. I personally use systemd-cron which basically is a
23 wrapper+generator around /etc/crontab and the various /etc/cron.*/
24 scripts.
