Using --build-on-remote targets i686-linux

[dustinlyons]

Describe the bug

When trying to build my x86_64-linux machine from my M1 Macbook, I get the following error:

Failed to find a machine for remote build!
derivation: bm173dm4why0gsh6h485v6q9dgz1r9gb-nv-codec-headers-11.1.5.2.drv
required (system, features): (i686-linux, [])
1 available machines:
(systems, maxjobs, supportedFeatures, mandatoryFeatures)
([x86_64-linux], 1, [], [])

Previously I was able to build this system successfully if running locally. The x86_64-linux machine in question is a local bare metal PC in my office, running the latest NixOS installer (23.05).

I'm unsure why i686-linux is being targeted here.

To Reproduce

Steps to reproduce the behavior:

I ran this on my local LAN:

nix run github:dustinlyons/nixos-anywhere -- root@192.168.0.134 --flake .#felix --build-on-remote -L

Expected behavior

I expect the system closure to be built. I'm unsure why ffmpeg headers are being targeted for i686-linux.

System information

Here's my code: https://github.com/dustinlyons/nixos-config

I'm inspecting the live installer ISO, the target of the remote build.

Running nix show-config:

extra-platforms = i686-linux x86_64-v1-linux x86_64-v2-linux x86_64-v3-linux x86_64-v4-linux

system = x86_64-linux

[multivac61]

I get similar issues when calling --build-on-remote when building for x86_64-linux on M3 mac. The nixos-configuration is gdrn from here https://github.com/multivac61/nixos-config.

The same configuration builds fine from another nixos x86 machine.
