Thanks for confirming. Why is it different? > What we could do is make it #t if and only if the URL denotes a local > file and that file is a directory.

What I expect is that 2 (fixed-output) files with the same hash (0ssi1w…) lives at the same store location… --8<---------------cut here---------------start------------->8--- $ guix hash /gnu/store/chariqd6k0sli3s7vcl4q3al0crirz5v-hello-2.10.tar.gz 0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i $ guix hash /gnu/store/hbdalsf5lpf01x4dcknwx6xbn6n5km6k-hello-2.10.tar.gz 0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i --8<---------------cut here---------------end--------------->8--- …whatever if these (fixed-output) files come from “guix download”, “guix build -S” or “--with-source=https://” or etc. The mapping from hash (0ssi1w…) to store location should be 1:1 for fixed-output, IMHO.
