From WordNet (r) 3.0 (2006) [wn]:

  derivation
      n 1: the source or origin from which something derives (i.e.
           comes or issues); "he prefers shoes of Italian derivation";
           "music of Turkish derivation"
...
      8: the act of deriving something or obtaining something from a
         source or origin

Seems like a some subtle variation of definitions 1 and 8, according to
wordnet. Closer to 8, really, so I'd say ...

The guix derivations are the result of processing or using (the act)
inputs (sources and origins) to produce an output (the derivation
itself).


I would guess the original Nix publication also explains the use of this
term?
