Ich erinnere mich an den Fall. Das stossende fand ich, dass er einen Arbeiter dazu aufgefordert hat ihm Käse zu geben. Aus der Autoritätsposition als Polizist heraus klingt so ein Forderung schon sehr ungut.
I’ve never seen any substantial evidence of a distro with outdated packages really being any more reliable than a rolling release.
I think the fundamental issue here is that you conflate the concepts of reliablility and stability. Those are not the same. Stability in distros is a question of how much they restrict change during support cycles in order to not be a moving target for developers and system integrators. Fundamentally a rolling release can't be stable. It can absolutely be reliable to use, but you wouldn't use it as a basis for an embedded system you're trying to develop.
No, it's a rolling release. Stable means that behaviours don't change during a support cycle of a major version. A rolling release can't be stable since it doesn't have major versions.
Pi-hole is nice for devices that you don't fully control. But it's not enough, due to the fundamental limitations of DNS based blocking. If the ads and the content are hosted on the same domain, it can't do anything.
But system32 contains the kernel as well, so that's worse. Uninstalling your init system still leaves you with single user mode. You could probably reinstall an init system from there.
He uninstalled systemd, now his computer is not doing systemd things anymore by his retelling. Seems like it worked fine. Yet he asks for a solution of a problem. Maybe he needs to state the problem.
