Description of problem: # sealert -l 68f0f3fb-624b-4a27-a269-34f3383d6ddb Summary: SELinux is preventing /usr/sbin/rpc.svcgssd "write" access on nfs_0. Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by rpc.svcgssd. It is not expected that this access is required by rpc.svcgssd 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.

This was dontaudited in the current policy, But I believe it should be allowed, since I think this is gssd writing a ticket to the credential cache. Fixed in selinux-policy-3.7.19-1.fc13.noarch
