This is not to answer your question, but to inquire about
the way "at" works vs "cron". Cron's behavior is controlled
by a cron table, edited using crontab. A daemon, crond, checks
the cron tables on a regular basis, to check if a periodic
activity is scheduled for execution. "at" has a similar
table /var/spool/{atjobs,atspool} where jobs scheduled for
one-time execution are queued. There a similar daemon "atd"
that checks the "at" spool from time to time to see if a job
is ready for execution. Who starts this daemon, and where is
it started? Is it started the first time root issues an
"at" command? Or is it started as part of the sysvinit
activity?
