I looked at that. Actually I would argue that was even more negligence by the management there. I mean they couldn't even say how long he'd not been working for.
But in reality he was paid for at least 6 years of work (and they suspected more) and only fined for 1 year of pay. So, he's still a winner I think. And yes, public funds likely did help in bringing that case forward.
Most larger private businesses tend to avoid going to a court for such things unless they need to in my experience.
Going to second other comments. Even without archinstall. It feels like it will be harder than it is. Umm, just save yourself a bit of time and configure the network and install a console editor (nano/vim whatever) while in the chroot (if going full manual). It was a minor pain to work around that for me.
There are pages discussing how to do everything (helps to have a laptop with browser, or a phone to look them up). At the end, you generally know exactly what you installed (OK no-one watches all the dependencies), and I've found any borks that happen easy to fix because I know what I installed.
