It's difficult to peddle. You notice the loose chain again so you tighten it by resetting the rear tire further back. It corrects the problem. Thus the loose chain MUST be the problem of a slow bike. And tightening it WILL fix it. Later the symptom returns. Bike is slow again. Worse, the rear tire is showing damage. Finally the chain jumps off the sprocket causing the bike to totally lock up crashing into the pavement. That damm loose chain! Meanwhile what really happened is that one of the rear bolts was partially stripped when someone tried to steal your bike. So that side of the rear tire started easing forward causing the rim to rub against the brake pad - thus slowing the bike. It eases forward a bit more because the bolt is still loose. The tire starts rubbing against that same screw again thus damaging the tire. It eases forward yet some more to the point that the chain is so loose it jumps off the sprocket. The rest is history. That cursed loose chain. It causes flat tires, it slows the bike down, and it causes it to crash and burn. You see, that loose chain is mearly a domino effect symptom of the root cause of the problem, that stripped bolt. Which in turn was caused by the guy who tried to steal your bike. And the tire damage is caused by that fender you installed using a screw that was too long, but only after the damaged screw (root cause) starts slipping. Fix that bolt (replace it) and you've corrected all the problems that you thought were caused by that "cursed loose chain". A Linux system is significantly more complexe than a bike. Potential for a domino effect impacting SELinux certainly exists. SELinux may APPEAR to be the root cause of all your problems. But it may only be part of a chain reaction rooted somewhere else on your system. SELinux may not be the cause, but perhaps the messenger, the visual cue, the "chain" that you've now developed tunnel vision for and blame for everything.
