Description Paul Bransford 2010-12-02 07:34:44 UTC
Summary:

SELinux is preventing /bin/mount "fowner" access .

Detailed Description:

SELinux denied access requested by mount. It is not expected that this access is
required by mount 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 FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Paul Bransford 2010-12-02 07:36:28 UTC
The media was mounted through the "Places" menu.

The media is in fstab, as such:
UUID=05fb8490-3ee7-4b13-8b1b-c24bce504828 /media/X0-640GB ext3 rw,nosuid,nodev,users 0 0

The mountpoint was created as root via "mkdir /media/X0-640GB"

The media was successfully mounted despite the SELinux denial.

Comment 2 Daniel Walsh 2010-12-02 14:49:09 UTC
Since it has dac_override it should probably have this also.  You would think one implies the other.
