Ya, I don't see any point in systemd adding this, but they did it already. Near as I can tell most of the laws just want to know a rough age category that can be provided by the OS. Seems to me an `echo "adult" > ~$USER/.config/law_compliance/age_category` would do the trick.

Anyone that cares can go check that file if they want an age category for some reason. Why does this need to be any more complicated?

If a parent really wanted, they could change the perms so only they could change that file.
