TL;DR for anybody worried. systemd-tmpfiles --purge was too broad in scope (and has a confusing name) so now you must be more specific when using it to avoid accidentally deleting things.
"Linux kernel was a blot, so here's our new kernel, written in system-langd, compiled using systemccd using the maked build system. Normal assembly was also a blot, so we came up with sasmd. The whole hardware is a blot, so we came up with hardwared. They're all tightly integrated. The name of the company does not vibe with our vision, so we are renaming it to ibmd. Your brain is also a blot, so here's braind. Now you can dump that outdated, prokaryotic fleshy crap and use systemd instead."
Imagine what would happen if one service goes down. Fucking hell, the Armageddon is real.
