I wrote an alternative Debian installer. It's a toy, but you can read about it on my blog.
@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.
@KnowPresent https://wiki.debian.org/RaspberryPiImages there are images being built for RPi 1-3 by people other than me already.
