[PATCH] install: Discover local substitute servers. |
|
Date: |
Thu, 3 Dec 2020 15:01:55 +0100 |
* gnu/system/install.scm (%installation-services): Add avahi-service-type and
enable substitute server discover in guix-service-type.
[<name-service-switch>]: Set it to %mdns-host-lookup-nss.
---
Hello,
This allows the installation image to use local substitute servers discovered
using Avahi.
It only increases the image closure by 10MiB.
Thanks,
Mathieu

Hey,
> How bigger is the resulting ISO?
It's 10MiB bigger! I took your remarks into account and pushed as
8361817bf693742757b096468198626f297bb09e.
Thanks for reviewing,
