Answering on arch-general as I can't post to arch-dev-public.
Because, while we're at it... I'm not very proud to add, don't use
sudo while moving around /etc/group.
I'm currently travelling and more or less only have this machine to
work with. As I haven't memorized any systemd boot flags, some time
later I finally found a way to get back up and running by setting
"init=/bin/bash"...
So, really, don't use sudo for /etc/{passwd,shadow,group,gshadow}.
cheers!
