Long story short, I wanted to test something with firewall disabled, had to first jump through hoops to uninstall firewalld, then tried using system-config-firewall, and recevied the following denial:


SELinux is preventing /usr/bin/python2.7 from unlink access on the file iptables.

*****  Plugin catchall_labels (83.8 confidence) suggests  ********************

If you want to allow python2.7 to have unlink access on the iptables file
Then you need to change the label on iptables
Do
# semanage fcontext -a -t FILE_TYPE 'iptables'
where FILE_TYPE is one of the following: system_conf_t, systemd_passwd_var_run_t, firewallgui_tmp_t. 
Then execute: 
restorecon -v 'iptables'


*****  Plugin catchall (17.1 confidence) suggests  ***************************

If you believe that python2.7 should be allowed unlink access on the iptables 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-f /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
