The Hallium Project is a noble effort but it's not something I would ever consider using in DebiaN900 or its successor. A unified HAL that encourages the use of Android kernels (many of which are EOL and unmaintained), Android blobs and systemd is an absolute no-go in my book. I think there is market for alternate OSs to iOS and Android but they must be secure and open if they are to be taken seriously. Unfortunately Hallium inherits many of the problems present in Android. I'd sooner switch to Replicant than embrace an insecure, binary blobified GNU/Linux distro. Hallium was part of my inspiration for why I made a new thread to start documenting open mobile devices.
