and wanted to use opendoas, maybe already know that there exist opendoas-sudo in AUR for drop-in replacement (symlink doas to sudo) so you can type sudo (and programs wich use sudo) instead of doas (for convenience).
But there was still a thing like visudo missing.
So i forked vidoas (see links below) and changed it for Arch specifics. And created a drop-in replacement for it too.
See:

AUR Links:

A maybe interesting Link regarding the Wiki:

You don't even need opendoas or any kind of third party program to install, just use su.
I even wrote a wrapper script:
#!/bin/sh
su root -c "$*"
If you just want to run certain commands as root without putting in any password, my project https://github.com/Lancia-Greggori/priv might interest you.
There are many ways leading to Rome :)
