    SELinux is preventing /bin/umount (mount_t) "getattr" to / (security_t).

Detailed Description
    SELinux denied access requested by /bin/umount. It is not expected that this
    access is required by /bin/umount and this access may signal an intrusion
    attempt. It is also possible that the specific version or configuration of
    the application is causing it to require additional access.

Allowing Access
    You can generate a local policy module to allow this access - see
    http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable
    SELinux protection altogether. Disabling SELinux protection is not
    recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
    against this package.
