- the reason for this change is to have more transparent separation of concern between effectuations of the module system and pre-module system effectuations - with improved flakes support down the line, pre-module system effectuations will get more complex - this also allows to patch the aspects of the evaluation individually while tracking other components from upstream. eg. path options & eval but not modules

Whether to build the system profiles on the target node itself.

When enabled, Colmena will copy the derivation to the target

the `push` goal. Since builds happen on the target node, the

results are automatically "pushed" and won't exist in the local

Nix store.

`--build-on-target` (enable for all nodes) or

If your Colmena host has nix configured to allow for remote builds

you can set a machines file that will be passed to the underlying

For example, if you support multiple orginizations each with their own
