I think it=E2=80=99s supposed to be propagated. In the example above, I guess there were cached ci.guix.gnu.org narinfos for those substitutes and the =E2=80=9Chost not found=E2=80=9D error arose = when actually trying to substitute these, right? I=E2=80=99m surprised substitution didn=E2=80=99t just crash. Thanks, Ludo=E2=80=99.
