Remember how systemd starting as root if the username starts with a digit isn't a bug? Turns out they're technically right. It's not a bug.
It's a bug worthy of a CVE. CVE-2017-1000082, which had to be requested by third parties. Like, I suspect, every systemd CVE ever.

End-users who have reasons for staying close to upstream, otherwise I have no polite opinions on that.
