I'm guessing that a lot of the substance of AROS is re-engineered linux. Nothing wrong with that, but it's certianly is'nt using the old code from Amiga OS 3.1. I did read the instalation and FAQ pages at the site some time ago, (They mention Linux/FreeBSD a lot)
I just downloaded and burned the boot ISO, and tried it out. Yes, it's nothing like Linux. But wait.. and Xbox is nothing like a PC either.
I'm not supper educated about it here, I don't know, I only tried it once. I did read up on it though.. and from what I understand they are using linux and the code from linux to expediate development, again, nothing wrong with that.
Anyway, they day I can boot Workbench 3.1 on my Game Boy, that's a dream of mine, neato-torpedo. How many geeks would but an alternative operating system for their portable devices for 29.99?
