Dear,
Using Guix 04a459a, the classical:
guix build dune
guix build dune --no-grafts --check -K
return:
--8<---------------cut here---------------start------------->8---
guix build: error: derivation
`/gnu/store/kg7mnb1b09n5zddgvc4hs8ira3i4jzz2-dune-1.11.3.drv' may not be
deterministic: output `/gnu/store/1wwdmzcjhrpal92sz2zwzhyqmbc3w7ri-dune-1.11.3'
differs from ‘/gnu/store/1wwdmzcjhrpal92sz2zwzhyqmbc3w7ri-dune-1.11.3-check’
--8<---------------cut here---------------end--------------->8---
then:
diff -r --no-dereference
/gnu/store/1wwdmzcjhrpal92sz2zwzhyqmbc3w7ri-dune-1.11.3{,-check}
returns a large output (truncated here):
--8<---------------cut here---------------start------------->8---

Is it expected? Does it comes from timestamp? Is it avoidable?
I have not tried (yet) with the patch [1] updating ’dune’.
