Yup, that's what I mean.

I think there's a bit of confusion about the terminology.
We have:

- small first stage loader ("kboot-stage1")
- the full Linux system(s) we normally boot
- a reduced Linux system that implements extended boot loader
  functionality (selection of other kernels, user input, etc.)

What I'm talking about is the latter. Petitboot is just a Linux
program that implements a good-looking GUI already designed for
this kind of boot loader. Using it just means one DIY item less
for us.
