If you don't understand how SELinux works why do you have access to a production environment that utilizes it?

1. Because I'm often the domain specialist in how a certain daemon works and I've been asked to debug some issue

2. Because the production environment didn't have SELinux, until the ops team that manages it read this blog article, and decided to enable it: but I still need to do my job.
