+Anyone who cares about security may want to switch from systemd as soon as possible; its lead +developer doesn't care about your security at all.
+Poettering:
+"You don't assign CVEs to every single random bugfix we do, do you?"
My thoughts:
+Yes, if they're security-related.

Poettering:
+"Humpf, I am not convinced this is the right way to announce this. We never did that, and half the
+CVEs aren't useful anyway, hence I am not sure we should start with that now, because it is either
+inherently incomplete or blesses the nonsensical part of the CVE circus which we really shouldn't
+bless..."
My thoughts:
+CVEs are supposed to be for security, and a log of when they were found and their severity, so yes,
+it *is* the correct way to announce it. It seems as if over 95 security-concious people think the
+same.

Poettering:
+"Yes, as you found out "0day" is not a valid username. I wonder which tool permitted you to create
+it in the first place. Note that not permitting numeric first characters is done on purpose: to
+avoid ambiguities between numeric UID and textual user names.
+
+systemd will validate all configuration data you drop at it, making it hard to generate invalid
+configuration. Hence, yes, it's a feature that we don't permit invalid user names, and I'd consider
+it a limitation of xinetd that it doesn't refuse an invalid username.
+
+So, yeah, I don't think there's anything to fix in systemd here. I understand this is annoying, but
+still: the username is clearly not valid."
My thoughts:
+systemd was the thing that allowed root access just because a username started with a number, then
+Poettering blamed the user.
