For those interested on the question of age verification and GNU/Linux: be aware that Systemd v261-rc1 was recently released. It now implements an optional birth date field in the JSON user database (see second item under “Other changes”).
The implementation of this field was prompted by age-verification or -attestation laws.
It’s always been thus, tho, I think?
Seems like our times are troubled enough that identity is become a powderkeg issue, which I can understand.
But I don’t think Debian is forcing us to inscribe our legal names here.
