If you have at but not cron, then implementing the

"wouldn't it make more sense for the run-stuff-at-some-time task to run
from the recurring-execution tool, than the other way around?".
I've never seen a *nix (since the 70s) that didn't have CRON (in one form
or another)... And on my FreeBSD system, "atrun" is called every 5
minutes, so /etc/crontab will need to be edited for finer granularity.
