You can build the `-A outputs.default` attribute to build an empty and
|
|
un-configured image. That image can be configured using `local.nix`.
|
|
|
|
** Note that an unconfigured image may appear to hang at boot. **
|
|
|
|
An alternative is to use one of the `examples` system. They differ in their
|
|
configuration. An example that should be building, and working using
|
|
cross-compilation is the `examples/hello` system. Read its README for more
|
|
information.
|
|
|
|
$ nix-build examples/hello --argstr device ${device} -A outputs.default
|
|
'';
|
|
})
