I read in the docs,etc that Selinux should be disabled. ItS not hard to get selinux working with magento and makes server way more secure.
Without selinux your site will be hacked just a matter of time. I am not saying with selinux you can't get hacked but way harder. Let's say I put a file on your server to execute without selinux that file would run malware as an example and you wouldn't know it before it was too late. With selinux it would block it and telling you do you want this program to run, etc
