This alert did not appear from the beginning and I think it could be something spread. Something similar later appeared for smartd. I'm new with mls policy and settings, but a good SELinux policy don't touch the Xorg ... I used SELinux permisive without kernel settings to load SELinux with kernel. This output is for : [root@desk mythcat]# sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: mls Current mode: permissive Mode from config file: permissive Policy MLS status: enabled Policy deny_unknown status: denied Memory protection checking: actual (secure) Max kernel policy version: 33
