i cannot for the life of my figure out how to do a nixos-rebuild with both --build-host and --target-host ... my admin machine is x86, but the build & target is aarch64 ... it should just be remotely requesting a build, but for some reason it fails with an error from a specific package about needing to build on x86... thing is, i can build it by sshing over, so why not with nixos-rebuild? #nixos
