Subject: [bug#77033] [PATCH] deploy: Support --target and --system.
Date: Mon, 17 Mar 2025 18:31:03 +0100

[Message part 1 (text/plain, inline)]

So, I tried building this machine on an aarch64 system with the qemu-bin
service running now a couple of times ...

```
(use-modules (gnu machine)
             (gnu machine hetzner))

(list (machine
       (operating-system %hetzner-os-x86)
       (environment hetzner-environment-type)
       (configuration (hetzner-configuration
                       (server-type "cx42")
                       (ssh-key "/home/roman/workspace/guix/id_rsa")))))
```

I used this command:

```
[roman <at> m1 guix]$ ./pre-inst-env guix deploy hetzner-minimal.scm --no-offload --target=x86_64-linux-gnu --timeout=864000 --max-silent-time=864000
The following 1 machine will be deployed:
  guix-x86

guix deploy: deploying to guix-x86...
guix deploy: warning: <machine-ssh-configuration> without a 'host-key' is deprecated

The following derivations will be built:
  /gnu/store/0ma7qrdd5pz8421rka75mvmvhkvn1rld-libxcrypt-4.4.36.drv
  /gnu/store/8js0zmi3c2zg7ks3qnpiwsckam37vi67-guile-3.0.9.drv

building /gnu/store/0ma7qrdd5pz8421rka75mvmvhkvn1rld-libxcrypt-4.4.36.drv...
```

And it always "hangs" there. I haven't much investigated this yet. Just
a small update.
