Aaah :-)  Yeah that makes sense.

Well, from my understanding, « fixed-output derivation without any
dependency » is not clear at first (we are always dependent on something
else ;-)) and I am sure that weeks or months later, I will not remember
that it means: « zero “sources” and zero “input derivations” ».

Hum, once it is known, it is hard to find a better wording though. ;-)

I do not know if it is better, at least, it appears clearer from my
point of view:

      "Return a fixed-output derivation that performs a Git checkout of REF,
    using the \"builtin:git-download\" derivation builder, thus without any
    dependency other than from builtin."


Cheers,
simon
