I literally saw that kind of message very recently on a nixos based machine and I literally had to stand up and do a lap. What in God’s green earth do you mean there’s no ‘sudo’??
If you follow the Arch installation guide it’ll get you to a working system, but you’ll need to install sudo yourself. It’s not strictly required so it’s not installed with the essential packages (or even the packages recommended for most users in the guide).
Surely any user planning on using arch would want sudo. I mean if Ubuntu desktop didn’t come with sudo I’d understand but arch? Linux From Scratch was a thing when I was still playing with Linux (rather than just using it) and that also was very much an if you want it, install it, but that suggested sudo as the likely alternative was the user would log in as root
apt remove sudo
sudo is not installed on several distributions by default, so hardly surprising it’s not there or that you can remove it.
It’s not surprising you can remove it, but it seems contrary to teaching good habits to not install it by default as a basic utility. You don’t want to train people to log in as root
Actually I think the only way I can log in as root is sudo -i
Pretty sure root has /bin/false as its shell and it’s configured as no login my machines
