Basically, you have a version of Grub available in
output/staging/sbin/grub that you can use to install Grub.

I'll try to clean up the script, but it unfortunately won't be this

fakeroot can do *some* things, but not everything.

There's one little sample script in the slides, do you more examples ?

My intention was to make improvements to the Buildroot documentation by
integrating some aspects of those slides.

Ah, okay, I never used the search engine for the mailing list archives.
