Description Patrick C. F. Ernzer 2010-06-04 10:14:54 UTC
Summary:

SELinux is preventing /bin/cp "relabelfrom" access on
/var/lib/dhclient/yp.conf.predhclient.br0.

Detailed Description:

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

Comment 1 Patrick C. F. Ernzer 2010-06-04 10:16:28 UTC
this is a fresh F13 install with /home from an older Fedora install.
files in /var/lib/dhclient/ were not knowingly touched
