<blockquote><p>"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.</p>

<p>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.</p>
|

<p>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."</p></blockquote>
