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.


Yes, right next to the fields for your full name and address, all of which are optional. It’s a total nothingburger.
Did you ignore the comment in the github where it, and I quote “Stores the user’s birth date for age verification, as required by recent laws in California (AB-1043), Colorado (SB26-051), Brazil (Lei 15.211/2025), etc.”. Yes it is optional NOW, but this is in preparation of laws that make it legally Mandatory. Don’t down play this.
Just like the room number when using the adduser command
Yeah just because they build cages for kids in the desert near the border doesn’t mean anything’s going to happen! It’s just optional infrastructure in case you want to put your kids in a cage. It’s totally voluntary.
There are genuinely useful use cases for it, and unlike what you suggest it is completely harmless.
Is everyone ignoring the direct quote in the orginal post that is referring to laws (California (AB-1043), Colorado (SB26-051), Brazil (Lei 15.211/2025)) that are going to force you to verify your age?
The California law does not require verification. Only attestation.
Not invested enough to be for or against it personally; just curious…
What are the user-beneficial use cases for it?
