rawhide strict & crond

[Holger Burde]

Hi;

It looked that way : 

[root at dragon bin]# ls -lZ /var/spool/cron/
-rw-------  root     root     root:object_r:sysadm_cron_spool_t apache

I created the cron entry as root/sysadm_r with the -u flag for user
apache. 

After i changed it to root:object_r:user_cron_spool_t it worked !
THX
