Add a required birth date prompt (YYYY-MM-DD) to the user creation flow, stored as a systemd userdb JSON drop-in at /etc/userdb/<user>.user on the target system.
Motivation
Recent age verification laws in California (AB-1043), Colorado (SB26-051), Brazil (Lei 15.211/2025), etc. require platforms to verify user age. Collecting birth date at install time ensures Arch Linux is compliant with these regulations.

The pull-request discussion thread has been locked, just like it happened for the similar thread in Systemd, owing to the amount of negative comments…
Imo, the move would be if all linux distros were to let the date come and go and just geo block all requests from countries and zip codes that do this. Users breaking the law would not be the problem of the organization making the OS. If they’re not “offering” the OS in those zip codes, refuse all service, patches, updates, everything, they would not be legally responsible.
