I'd like to make a custom ISO with it's own pre-configurations such as a custom desktop and a custom browser with plugins. How would I achieve this?
Have you looked at the wiki ?
https://wiki.artixlinux.org/Main/InstallationUsingBuildiso
Does this allow exact pre-configuration or does it create an install list?
I think so, because this section of the wiki starts with this sentence:
"It is possible to create a custom bootable ISO by following the procedure below."
So you can only use lxqt for a desktop environment in ISO creation? This guide is a bit unclear
I'm getting a bunch of errors when running the commands in a root terminal and in a regular one, one of these being
error: failed retrieving file 'multilib.db'
But when I run sudo pacman -Sy all repos sync fine.
A kind contributor of this forum had already answered you on this subject :

But using a search engine, it is easy to find additional information on this subject :

I don't know if this has something to do with the multilib repository ?
https://forum.artixlinux.org/index.php/topic,132.0.html
Or with gcc ?
$ pacman -Ss multilib
system/gcc 12.2.0-1 (base-devel) [installé]

Copy /etc/pacman.conf to ~/.config/artools/pacman-default.conf and enable non-default repositories.
