22 I had a look at files and docs on the net again. Thus I found exactly those
23 rm entries in /etc/crontab, which by itself is not used by fcron. But after
24 I understood all the logic behind it, I added them to fcron to be run
25 serially before run-crons. Now everything is as I wanted it.
26
27 For the record: The checks in run-crons that I referred to earlier are
28 actually more for those cases in which the machine was powered off for a
29 while in order to restore cron completeness as early as possible after boot.
