That=E2=80=99s what it does, except for URL syntax errors.

That is, if you pass:

  --substitute-urls=3D"http://example.org/does-not-work https://mirror.hydr=
a.gnu.org"

then the first one is ignored.

Does that make sense?

Indeed.  Fixed in 8a2105078b5845e31768da06b360676352b1f3e9 (you won=E2=80=
=99t
get the fix until you run an updated guix-daemon.)

Thanks!
