A bit more on this:
[root@tlondon ~]# ps gaxZ | grep crond_t
system_u:system_r:crond_t:SystemLow-SystemHigh 2639 ? Ss 0:00 crond
system_u:system_r:crond_t:SystemLow-SystemHigh 2656 ? Ss 0:00 /usr/sbin/atd
system_u:system_r:crond_t 4295 ? SNs 0:00 /usr/sbin/acpid
system_u:system_r:crond_t 4307 ? SNs 0:00 cupsd
[root@tlondon ~]#
Should acpid and cupsd be running as crond_t?
[root@tlondon ~]# ls -lZ /usr/sbin/acpid
-rwxr-x--- root root system_u:object_r:apmd_exec_t /usr/sbin/acpid
[root@tlondon ~]# ls -lZ /usr/sbin/cupsd
-rwxr-xr-x root root system_u:object_r:cupsd_exec_t /usr/sbin/cupsd
[root@tlondon ~]#
Is there a missing transition (or some such)?
