I've run my home systems with SELinux on for some time.
Good for you. Last I looked adding a printer using lpadmin with SELinux enabled created a situation where the printer worked perfectly... until the system was rebooted, and then it was as if you had never executed any of your lpadmin commands.
"Security" is supposed to do less damage to you than to the other guy. I'm not at all sure that SELinux achieves that goal except in certain select circumstances.
