I don't get this. What is Network Manager doing with /dev/root? Also,
Network Manager is not enabled in chkconfig.
Summary:
SELinux is preventing nm-system-setti (NetworkManager_t) "getattr" to
/dev/root
(fixed_disk_device_t).
Detailed Description:
SELinux denied access requested by nm-system-setti. It is not expected
that this
access is required by nm-system-setti 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 /dev/root,
restorecon -v '/dev/root'
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.
