Configurable boot and swap partitions about amis HOT 3 OPEN

How i've been personally tackling deploying to t4g.micro is by doing the evaluation and building outside of the instance. And have the instance pull the build on startup.

Instead of setting the user data to a nix configuration: that is built locally on the instance; I set the user data to a shell script that downloads the already built nixos configuration:
e.g. set the user data of the instance to:

  user_data = base64encode(<<-EOF
  #!/usr/bin/env bash
  set -e
  nix build '${var.nix_store_path}' \
    --profile /nix/var/nix/profiles/system \
    --experimental-features 'nix-command' \
    --extra-substituters '${local.nix_substituter}' \
    --extra-trusted-public-keys '${local.nix_trusted_public_key}'
  /nix/var/nix/profiles/system/bin/switch-to-configuration switch
  EOF
  )

And in CI:

nix copy --to my-cache .#nixosConfigurations.myserver.config.system.build.toplevel

Or if you're doing push based deploys:

nixos-rebuild switch --target-host  <the-ip-of-the-instance>

For the /boot problem I think we can try to make the /boot partition a bit larger. I'll look into it.

I was completely oblivious to the fact that you can remotely build configurations, I'll definitely look into this!
