1. Request the list of all SELinux Booleans and selectively show those starting with httpd_:

   ~# getsebool –a | grep httpd_

   ~# semanage boolean –l | grep httpd_
   

3. If the description of a Boolean isn't sufficient, we can ask the SELinux utilities to display the SELinux rules that will be ...
