The difference between these two derivations is the build script. In the second case, it reads this: --8<---------------cut here---------------start------------->8--- (define %build-inputs (quote (("source" .

The repetition stems from the traversal done by ‘bag-transitive-inputs’, which relies on pointer identity when comparing packages (via the ‘eq?’ vhash in ‘transitive-inputs’), and for some reason there are two non-eq? linux-libre-headers packages encountered here. ‘master’ doesn’t have this problem. FTR we had a similar issue in <http://bugs.gnu.org/20037> with PAM services. Incidentally, I discovered this bug while getting berlin.guixsd.org to build ‘core-updates’: Cuirass there would exhibit the bug, and thus berlin would end up building something different from what I have on my laptop (and what hydra.gnu.org has.)
