Simple age check for Linux:

Just have the shell ask the user to check the host IP on first boot.

If they type ifconfig they are old enough, if they type ip they deserve to be restricted from their computer 😇

@stacksmashing if their host has more 3 active physical network interfaces, they clearly know what they're doing and know more than any dumb politician. If they only have IPv6 active then they know more than most ISPs.
@zymurgic @stacksmashing last time I tried it wasn't possible to have an IPv6 only host. I couldn't delete 127.0.0.1 :(
