Is there anything special I need to do to activate password-less sudo? I edited the sudoers file to enable the option but I'm still promoted for a password each time.

I *think* this is all you need in /etc/sudoers:

root ALL=(ALL:ALL) ALL

Is that ALL?

Just use the root account :) Even if it is frowned upon as a security risk.

setuid doesn't actually work for shell scripts, anyway.

Better (more secure) than using the no-password feature of sudo, is to
use "gksudo <command>" (which uses a GUI dialogue to prompt for the
password, so is not a problem when not using a terminal) in the script.

One of my first things every time I set up a new system is to...

sudo passwd

and open up the root account. If your system isn't open to the outside world its hardly a security risk. Although I'd still recommend a decent password. Bets the hell out of sudo this, sudo that and sudo something else.

Not quite:

%wheel ALL=(ALL) NOPASSWD: ALL

This allows anybody in the wheel group to use sudo without a password. Add
yourself to the wheel group, log out, and log back in, and you're all set.

The wheel group? I haven't seen that in years, and not on any active system, where are you from? :)

Manjaro (which is what I use) uses the wheel group for whatever reason.

Most of the Linux boxes I run use Gentoo Linux, where it's very much still a
thing. None of that systemd rubbish, either, unless you want it for some
strange reason.

Totally off-topic, but I have learned to like systemd. I used to be a sceptic too.
