In reply to @plg:matrix.org
Hi, I'm trying to convert a set of configs in a flake that all use lib.nixosSystem. I'd like to do them one by one, and keep outputs.nixosConfigurations as is for a bit.
Is it possible to use the result of nixosSystem with colmena?

Colmena is throwing this error message when I try to deploy a flake:

[ERROR]   stderr)        Failed assertions:
[ERROR]   stderr)        - The ‘fileSystems’ option does not specify your root file system.
[ERROR]   stderr)        - You must set the option ‘boot.loader.grub.devices’ or 'boot.loader.grub.mirroredBoots' to make the system bootable.

But the root filesystem is specified. I tried setting it directly in the colmena block like git shows and it's still complaining

Colmena itself doesn't use nixosSystems and you need to define the system configurations in outputs.colmena.<name>
