and run `$(nix-build --no-out-link krops.nix)` to deploy the target machine.
krops exports some funtions under `krops.` namely:
Under the hood, this will make the sources available on the target machine
## writeDeploy
This will make the sources available on the target machine
below `/var/src`, and execute `nixos-rebuild switch -I /var/src`.
## Deployment Attributes
### `target`

Create the sentinel file (`/var/src/.populate`) before syncing the new source.
## writeTest
Very similiar to writeDeploy, but just builds the system on the target without
activating it.
This basically makes the sources available on the target machine
below `/var/src`, and executes `NIX_PATH=/var/src nix-build -A system '<nixpkgs/nixos>'`.
### `target`
[see `writeDeploy`](#writeDeploy)
### `backup` (optional, defaults to false)

## writeCommand
This can be used to run other commands than `nixos-rebuild` or pre/post build hooks.
### `command`
A function which takes the targetPath as an attribute.
Example to activate/deactivate a swapfile before/after build:
```nix
pkgs.krops.writeCommand "deploy-with-swap" {
source = source;
target = "root@YOUR_IP_ADDRESS_OR_HOST_NAME_HERE";
command = targetPath: ''
swapon /var/swapfile
nixos-rebuild -I ${targetPath} switch
swapoff /var/swapfile
'';
}
