Description Will Briggs 2008-11-13 22:34:50 UTC

Hi, I have vixie-cron-4.1-r10 installed.  Every script linked to or placed in /etc/cron.daily is run twice.  This is every day, not just DST, so not http://bugs.gentoo.org/show_bug.cgi?id=69777.  And I don't have anacron installed, so not http://bugs.gentoo.org/show_bug.cgi?id=235174.  

ps ax | grep cron shows only one cron process running.

scripts in cron.weekly, cron.monthly etc. don't seem to be affected.

I have done my best to check various crontabs to seeI wondered if there's something broken there.  I present them in case I've missed something (an etc-update along the way or something?)

Root's crontab (crontab -e)

*/15 * * * *     test -x /usr/sbin/run-crons && /usr/sbin/run-crons
0  *  * * *      rm -f /var/spool/cron/lastrun/cron.hourly
0  3  * * *      rm -f /var/spool/cron/lastrun/cron.daily
15 4  * * 6      rm -f /var/spool/cron/lastrun/cron.weekly
30 5  1 * *      rm -f /var/spool/cron/lastrun/cron.monthly

and /etc/crontab is

Reproducible: Always

Steps to Reproduce:
1.Have script in /etc/cron.daily 
2.It runs twice (I have a number of scripts that email me on completion so I know)

Actual Results:  
/etc/cron.daily scripts run twice

Expected Results:  
/etc/cron.daily scripts run once

No, this is just a feature of sys-process/vixie-cron. /etc/crontab is the system's crontab and `crontab -u root -l` is root's crontab. If you have duplicate entries for running /etc/cron.daily in those two crontabs, then yes, you will see the scripts in /etc/cron.daily being run twice:

/etc/crontab:
0  3  * * *      rm -f /var/spool/cron/lastrun/cron.daily
root's crontab:
1  3  * * *     root    rm -f /var/spool/cron/lastrun/cron.daily

> root's crontab:
> 1  3  * * *     root    rm -f /var/spool/cron/lastrun/cron.daily

I got those mixed up, sorry. The former is root's crontab and the latter is /etc/crontab (as explained in crontab(5)[URL], which notes that only the system crontab has a user field. :)
