sure - no offense, but do you have read this thread? Or what passage of
the man page are you referring to?

To repeat the issue: I _am_ using anacron. With the default config anacron
is only started at system startup and at 7:30 AM once a day, but only if
the computer is running at that time. Thus if you only suspend your
computer all the time - and it is never online at 7:30 - anacron is
never ran again. I.e. anacron needs to run at least one time a day.
