I’ve managed to get Aranym to boot m68k Debian, although getting networking going is another matter. The initial problem was with my config having the incorrect disk geometry (thanks to arosfan for making me double check my settings).
I’ve also been looking at getting the m68k unmaintained compile going again on x86, but have not had much luck with this to be honest. I’m still trying to get my head around the weird AROS build process.
No doubt I shall have to pop over to #aros for a chat with some devs soon.
