Thanks Elais. This is exactly what I need.
Also you're right regarding the ISO running out of space (memory) as I ran =guix pull= once before the store was setup and mounted on the target system.
Also pinning the channels is useful to get "identical" os installed across the machines.
This might be a neat code excerpt and note in the manual perhaps. Would you agree?
Of course, once the system is setup then there is =guix deploy=.
