Bug 540976

Summary:

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

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

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 entire
file system.

Allowing Access:

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