Description twentydbk 2009-12-07 19:56:16 UTC
Summary:

SELinux is preventing /usr/bin/python "dac_override" access.

Detailed Description:

SELinux denied access requested by system-config-s. It is not expected that this
access is required by system-config-s 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2009-12-23 17:40:21 UTC
You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
