Neat, thanks for this article!

Question: how do you intend to convert the markdown to Texinfo?


Some typos / nits below:

Maybe define initramfs?  Or just link to https://en.wikipedia.org/wiki/Initramfs.

AHCI

Word missing here: "when the contain".

Maybe add "(notice the '_' and the '-' difference)."

Word missing: "we would the installer iso".

Also: iso -> ISO.

Isn't this a bug in Guix?
