Maybe we really need to deliver our own SELinux policy allowing it on F-16. Right, I don't see this working on F-16. I don't really want to carry this type of policy.

If reload is enough, I think the command should be named reload_httpd Yes, it causes the modules to be reloaded which will reload the NSS database, that's all we need.
