# XXX: this triggers another config eval & (potentially) build.
# if the config changed between these invocations, the above signatures might not apply to the deployed config.

# let the user handle that edge case by re-running this whole command.
# N.B.: `--fast` option here is critical to cross-compiled deployments: without it the build machine will try to invoke the host machine's `nix` binary.
# TODO: solve this by replacing the nixos-build invocation with:
# - nix-copy-closure --to $host $result
# - on target: nix-env set -p /nix/var/nix/profiles/system $result
# - on target: $result/bin/switch-to-configuration
