I just found this topic and read through it. It is a nice roadmap for AROS development.
I noticed some discussion around a Linux distribution. As a long-time Linux user and administrator since I stopped using my Amiga in 1999, I am quite familiar with the OS. I think creating an entire Linux distribution is kind of a lot of work. The effort presented here could be made into some software package for an existing distribution which configures it to behave as closely as possible to how a classic Amiga behaved. Automatic login and running of IntuitionWM is relatively easy.
