Bug 671651

Summary:

SELinux is preventing /bin/mount "write" access on /etc.

Detailed Description:

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

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.
