Google compute engine fails to run google-startup-scripts.service

[mrkkrp]

Describe the bug

With current nixpkgs, commit 34ad3ffe08adfca17fcb4e4a47bb5f3b113687be, Google compute engine uses this systemd service to run startup scripts (metadata startup script and such):

https://github.com/NixOS/nixpkgs/blob/f442ae9fc1a1f5a08d503dcedd490823a034af19/nixos/modules/virtualisation/google-compute-config.nix#L154-L170

As you can see it expects ${gce}/bin/google_metadata_script_runner to exist, which used to be the case, but for some reason, it's not there anymore:

$ ls /nix/store/y3nxrn3z6q6afqqhmrfdgwx2w56sqvj9-python3.9-google-compute-engine-20200113.0
lib  nix-support

The bin/ subdirectory is not there.

This means, that google-startup-scripts.service is going to always fail now and whatever setup it performed is not performed anymore. Which means nothing works anymore.

All the guest features are now handled by the google guest agent. https://github.com/GoogleCloudPlatform/guest-agent#features

We need to update that module to use the agent instead of the legacy python scripts. WIP there: https://github.com/NinjaTrappeur/nixpkgs/tree/nin/gce-fix
