Thanks Ludo'!


Vagrant has valid points about the patches.

Stefan do you want to address them or shall I?

I can confirm the Raspberry Pi 3 can run Guix, but when I attempt to do simple 
`guix pull` it fails due to running out of memory (has just 1 GiB) therefore 
there is probably no point to run on less powerful boards.

Not sure if the computation can be offloaded by using substitutes.

It runs fine on Raspberry Pi 4 where there is 4GiB of memory (at least in my 
case :) - the variant with just one 1GiB would have probably same result as 
RPi3.
