@Wolf480pl It feels really good to just have your trusty OS, which you know and take care of
However it might be good to do a cleanup from time to time. Even if you're on a rolling release, one day you might say, that luks on lvm is better that lvm on luks, or some other thing like that. Getting to know different package managers/init system, or general stuff, is probably good too. But that is for professional learning, and not for personal installation.
