What is the reason to shy away from Ubuntu? It is pretty solid in terms of automatic updating and rebooting. I used to be hardcore centos but I gave up after all of the hubbub around 8. I just need to server to update, reboot when necessary and keep running all my stuff so I don’t have to touch it. In my old age, I don’t care to tinker anymore - I just want my services running and I want reports given to me about health and status.
Also, if you’re concerned about privilege escalation, running a MAC is probably a good idea. SELinux saved my hide one a dozen years ago with a php bug where I did not sandbox an app properly. Thankfully, SELinux caught this and prevented anything bad from happening.
As for SELinux: I’ve tried around a year ago. But as soon as I started doing stuff with users and tweaking docker permissions things went wrong and I just set it to permissive. Maybe I’ll try that again soon, because other parts of managing servers have become much easier over time as I learned. I agree that having a server without SELinux is quite dumb and not very professional.
Permissive mode is definitely a life saver. My path was usually exercising the application in permissive mode for a few days then running the SELinux scanner on the log file to determine what roles needed to be setup. Same with the Debian/Ubuntu equivalent.
Good luck!
