I found that for me, SELinux is best mastered by reading the documentation. Most tutorials I read when trying to make custom policies and monitor how policies were working, were hot garbage written by people who were just reading other people’s tutorials. SELinux solves problems orthogonal to FS permissions, and use cases that FS permissions alone don’t address. It was a bit tough at first but writing your first SELinux profile is a fantastic way to make it approachable. YMMV, of course.
