Great blog post, thank you! It makes me a little hesitant about 
Zephyr if they have just given up on other people building their 
SDK, but I am very glad all of you smart people are working on a 
Guix alternative.

I am still curious if other parts of Guix System could be useful 
in embedded environments if all of the packages are 
cross-compiled.

I am not sure of the detailed plans for Oniro, but I assume that 
it will provide some sort of abstraction layer and user space on 
top of either the Linux kernel or the embedded Zephyr kernel. 
Would it be possible to make some subset of Guix System into 
something equivalent or is an entirely new operating system really 
necessary for that purpose? Are most of the resource requirements 
for Guix System, 1 Gig of ram, etc, due to the package builder and 
Guix/Nix daemon? If it was possible to declare an instance of Guix 
System that did not include those and only used cross-compiled 
packages, could some portion of Guix System function in a similar 
way as Oniro, or is that a nonsense question?
