‘guix system extension-graph’ is an attempt to help with that, by
showing how pieces are connected together, but it doesn’t show the whole
story…

Unfortunately derivations are comparable to assembly without debugging

(There’s no easy way to fix that, notably because .drv live in the same
global store and different sources can lead to the same .drv.)
