Whilst I don’t want to work on Linux on my Mac (I have many other machines to use for that), I am delighted that this work exists. It’s a fantastic initial effort and, if successful, with guarantee a users investment in this new Apple hardware even after Apple has stopped supporting it.
For those of us who only want to use MacOS on our Macs, the lessons learned here may also be useful in developing the necessary hacks for a future incompatible-with-first-gen-m1 MacOS to be made compatible. (Just as I can run MacOS 12 Monterrey on my 2009 Mac Pro now)
All in all, a happy story in dark times. A story with no downside!
