If IC Jobs are mimicking Unix cron in a way, how about adding support
for special time specification in style of Unix cron, but instead of
@reboot like in Cron, we'd call it @startup and/or @reconfig.
It would run in catalog context, after catalog is configured,
and once for @startup, or each time for @reconfig.
