For successful lookups, this is usually a long TTL (see > =E2=80=98guix publish --ttl=E2=80=99). For negative lookups, there are = two cases: a > 1h-or-so TTL for =E2=80=9Cabsolute no=E2=80=9D, and a 5mn TTL for > =E2=80=9Csubstitute-being-baked no=E2=80=9D. So my question is how I can influence/change that behaviour for my client? Because the current situation on my laptop is awful. And if it doesn't get better I will move away that system from Guix System...
