Never heard about this. They’re website is awesome, they have a extensive list of changes they made. Don’t agree with removing SELinux though. It stops enough security issues and it doesn’t seem good to have such a change while likely (didn’t check) rely on Fedora for package updates.

Kind of wonder how old certain changes are, e.g. Fedora did change the vm.max_map_count.

Edit: forgot to say that I do like it. I like opinionated software/projects even if I might not use it myself.
