What I wonder about is when it comes to Anubis is "why Linux?"
I mean, Linux is a very moving target, trying to build ontop of it is hard enough for dedicated Linux distros, GNU (toolchain) and everyone involved. For a handfull of people to create a "new OS" ontop of it seems like a heck lot of work, and work that will have to be redone on a regular basis as the Linux kernel moves on. Maintaining kernel patches is not fun, and maintaining kernel patches that will _never_ go upstream is even less fun.
So, why not pick a less "mobile" kernel, one with developers who actually know what AmigaOS is?
Say, DragonFlyBSD?
Also, even from reading the homepage of Anubis, I dont grasp what it's really about - it sounds like a OSX wannabe with linux as kernel and GNUStep as toolkit - nothing Amiga about it. Changing names of directories away from posix standard doesnt really do much.
So I have my doubts about this, and the fact that BBRV has somehow embraced it just makes me even more skeptic.
But, by all means, bring it on in whatever way you like :-)
