However, =E2=80=98proxy=E2=80=99= in (guix > inferior) doesn=E2=80=99t forward build output to =E2=80=98current-build-= output-port=E2=80=99. > That=E2=80=99s why there=E2=80=99s no message saying what=E2=80=99s being= built, no spinner, etc. > > I=E2=80=99ll see what can be done. Not surprisingly, to fix it, we need to implement a proxy that interprets all the messages exchanged so that it can write to =E2=80=98current-build-output-port=E2=80=99 when appropriate (that=E2=80=99= s the usual all-or-nothing problem with proxies.) For the daemon rewrite in Scheme, we=E2=80=99ll need to have server stubs anyway, so perhaps that=E2=80=99s an opportunity to fiddle with that. Cale= b? Ludo=E2=80=99.
