Description of problem:

Summary: SELinux is preventing dhcdbd (dhcpc_t) "read" to /etc/dbus-1/system.d

Detailed Description:

SELinux denied access requested by dhcdbd. It is not expected that this access
is required by dhcdbd 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 /etc/dbus-1/system.d,

restorecon -v '/etc/dbus-1/system.d'

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.

Additional info:
"restorecon -v '/etc/dbus-1/system.d'" does not fix this -- the context is the same before and after.
