Dylan, useful idiot with commit access, pushed age verification PRs to systemd, Ubuntu & Arch, got 2 Microslop employees to merge it, called it 'hilariously pointless' in the PR itself, then watched Lennart personally block the revert. Unpaid compliance simp.
The systemd change ‘just’ adds a birthday field to the user data, where you could store (or don’t) the users birthday, that then could be used by other applications to request an age bracket.
The Arch-change doesn’t effect real arch Linux. It modifies the archinstall script (so, irrelevant, if you install according to Wiki) to ask the user for their birthday during installation and stores it for systemd.
