SELinux vertigo- do you get it as well?

The more I know about SELinux, the more I hate it. Is it thoroughly hated but used in production or you decide to not use it whenever possible?

It's used in Production - and hated.

It's an essential security layer, however, I have seen more programs that don't support it than the other way.

Reading a book on it at the moment, in theory it's great but as mentioned integration with other apps seems to be poor.

never turn it off! this way you learn something every day and in the end you have some extra security along with grey hairs

Its a difficult concept to grasp, but once you get it down you understand why its necessary. You can usually get it to work with apps that aren't' supported natively however it can require considerable configuration changes. I'm not going to lie though, it took me reading over SELinux documentation multiple times to understand its functions and configurations.

I'm starting to get it, which is an awesome feeling.

The best tutorial I found is this: https://wiki.gentoo.org/wiki/SELinux

There are a number of tutorials on youtube which have also helped me.

Yes, I was like everyone else. At first I set it to disabled, however I kept at it and now I'm getting it.

One other possibility is the use of HIPS in place of SELinux. Even then you want to keep it in permissive mode for logging purposes.

Found 2 YouTube videos that are pretty much the same from RedHat and RedHat Summit that explain SELinux really well.

SELinux is awesome... once you learn how to deal with it.
