SELinux denial - F12


Installed F12 and did a security update. Now, I get SELinux denial error. 
SELinux currently in permissive mode.


SELinux is preventing access to files with the label, file_t.

Detailed Description:

SELinux permission checks on files labeled file_t are being denied. file_t is
the context the SELinux kernel gives to files that do not have a label. This
indicates a serious labeling problem. No files on an SELinux box should ever be
labeled file_t. If you have just added a new disk drive to the system you can
relabel it using the restorecon command. Otherwise you should relabel the 
file system.

Allowing Access:

You can execute the following command as root to relabel your computer system:
"touch /.autorelabel; reboot"

Any idea why this happened after the update? What could be done to prevent 
this. I am quite a newbie in SELinux scenario. Does, restorecon command fix 
(restorecon /usr/libexec/gdm-simple-greeter)?
