I wrote an alternative Debian installer. It's a toy, but you can read about it on my blog.
@joeyh It would be a fun hobby, except I keep having fights with grub and grub-installer. Pretty much everything else is easy.
@liw This looks great! Any chance you are thinking about what it would take to make this work on ARM? Would be really cool for building RPi (Raspbian) or Armbian systems.
