Under the hood, this will make the sources available on the target machine
below `/var/src`, and execute `nixos-rebuild switch -I /var/src`.

+## Source Types
+
+### `derivation`
+
+Nix expression to be built at the target machine.
+
+Supported attributes:
+
+* `text` -
+ Nix expression to be built.
+
+
+### `file`
+
+The file source type transfers local files (and folders) to the target
+using [`rsync`](https://rsync.samba.org/).
+
+Supported attributes:
+
+* `path` -
+ absolute path to files that should by transfered
+
+* `useChecksum` (optional) -
+ boolean that controls whether file contents should be checked to decide
+ whether a file has changed. This is useful when `path` points at files
+ with mangled timestamps, e.g. the Nix store.
+
+
+### `git`
+
+Git sources that will be fetched on the target machine.
+
+Supported attributes:
+
+* `url` -
+ URL of the Git repository that should be fetched.
+
+* `ref` -
+ Branch / tag / commit that should be fetched.
+
+* `clean.exclude` -
+ List of patterns that should be excluded from Git cleaning.
+
+
+### `pass`
+
+The pass source type transfers contents from a local
+[password store](https://www.passwordstore.org/) to the target machine.
+
+Supported attributes:
+
+* `dir` -
+ absolute path to the password store.
+
+* `name` -
+ sub-directory in the password store.
+
+
+### `pipe`
+
+Executes a local command, capture its stdout, and send that as a file to the
+target machine.
+
+Supported attributes:
+
+* `command` -
+ The (shell) command to run.
+
+### `symlink`
+
+Symlink to create at the target, relative to the target directory.
+This can be used to reference files in other sources.
+
+Supported attributes:
+
+* `target` -
+ Content of the symlink. This is typically a relative path.
