Could we add a config entry somewhere, say /etc/x2go/somefileorother,
where it says "ALLOW_NUMERIC_USERNAMES=false" as a default, and users
that have the need to use such usernames can set it to true in that
central location?  Feel free to attach a warning message that enabling
this is not recommended, may introduce errors and security issues (see
systemd's "0day" account bug), HC SVNT DRACONES, yadda yadda yadda.

Kind Regards,
Stefan Baur
