Bug 536755

Summary:

SELinux is preventing /bin/plymouth access to a leaked fifo_file file
descriptor.

Detailed Description:

[plymouth has a permissive type (plymouth_t). This access was not denied.]

SELinux denied access requested by the plymouth command. It looks like this is
either a leaked descriptor or plymouth output was redirected to a file it is not
allowed to access. Leaks usually can be ignored since SELinux is just closing
the leak and reporting the error. The application does not use the descriptor,
so it will run properly. If this is a redirection, you will not get output in
the fifo_file. You should generate a bugzilla on selinux-policy, and it will get
routed to the appropriate package. You can safely ignore this avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385)
