Why would this need "special software" btw?
I was going to ask the same thing, I very rarely see any drivers on a CD for hardware, since almost all of it is handled and is in the kernel.
Yes, udev is part of systemd, you just entered dragon territory.
As you pointed out, why any special software? Copy the udev rules over and you're good to go. Why would this depend on a specific version of libudev? And even if it did, they actually DO use backward compatibility.
Wrong, it has _nothing_ to do with open source, it's just not the goal of certain popular Linux distributions.
It sounds me to that you would be much more at home running NetBSD, for example.
Yeah, not sure what the beef with Linux is that he has. A while ago I bought Heavy Gear 2 for Linux. Guess what? Even though it came out in 2000, it still works on my Debian Sid desktop. That's 16 years ago, for a very much proprietary game. This "Linux changes all the time!" is a mantra that Microsoft and the BSD guys have thrown out there to try to discredit Linux.
Granted, as you said, systemd is a whole different beast. It's still pretty heavy in development, but the api level stuff is all pretty solid, otherwise RedHat wouldn't have put it into RHEL7.
Back on topic; If AmigaOS went open source, even now, it'd help all of the AmigaNG projects, not to mention just improvements all around. Would be nice to get updated kickstarts as well so we wouldn't have to use reboots to get it patched up to newer standards.
Even if no one was interested in hacking on it, it'd be good to be able to look through the code for academic reasons. Personally I like looking at how operating systems are designed and how they're used, so from that perspective having source available is fantastic.
