Description Craig Robson 2009-12-05 16:13:07 UTC
Summary:

SELinux is preventing /bin/fusermount "dac_override" access.

Detailed Description:

[fusermount has a permissive type (xguest_t). This access was not denied.]

SELinux denied access requested by fusermount. It is not expected that this
access is required by fusermount 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.
