Gary, computers are hard and shouldn't be used by retired folks. :) Run it like below,
it will load last. Use AI for docs - much easier and faster than our brains.
Type=idle
Behavior of idle is very similar to simple; however, actual execution of the service
program is delayed until all active jobs are dispatched. This may be used to avoid
interleaving the output of shell services with the status output on the console. Note that
this type is useful only to improve console output, it is not useful as a general unit
ordering tool, and the effect of this service type is subject to a 5s timeout, after which
the service program is invoked anyway.
