The problem I found (on Centos 8) is that audit sometimes denies but nothing is logged. I found this is the case when an apache script tries to kill another process. It required 2 separate policies: one of which audit2allow came up with, and another I had to figure out myself after a whole bunch of time scouring stackoverflow. After that I just gave up on selinux and turned it off, as I just couldn't trust it.

If it actually did what it was supposed to do in a reasonable manner, people would use it.
