There seems to be other (bug #804083) SELinux related problem with
'firewall-cmd --set-default-zone'.

SELinux is preventing /usr/bin/python from execute access on the file /usr/bin/bash.

I've been looking at the code but can't find anything 'bash' related so I have no idea what could cause the warning.

I still see this with selinux-policy-3.10.0-116.fc17
and still have no idea what could cause it.
Comment 3 Daniel Walsh 2012-04-20 11:20:19 EDT
We should just allow it.   Probably something to do with executing python with in a bash environment.
Fixed in selinux-policy-3.10.0-117.fc17
