AVC Denials x2 - No Network Connection Long-Post

Basically this is F9 on a USB-Stick, installed as "install to hd"
upgraded full to newkey status.
restorecon -v '/var/lib/dhclient/dhclient-eth0.leases'  -:- No change to avc(s)

Summary:

SELinux is preventing consoletype (consoletype_t) "read" to
/var/lib/dhclient/dhclient-eth0.leases (dhcpc_state_t).

Detailed Description:

SELinux denied access requested by consoletype. It is not expected that this
access is required by consoletype 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:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for /var/lib/dhclient/dhclient-eth0.leases,

restorecon -v '/var/lib/dhclient/dhclient-eth0.leases'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
