Description Roman Rakus 2011-11-17 23:35:38 UTC
SELinux is preventing /usr/bin/python from execute access on the file grubby.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that python should be allowed execute access on the grubby file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep system-config-k /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
