I would say that no, there are not plans, but only because I think its better to
experiment at this stage. But I have naturally started to use nix to build
configurations, so I have different convenience functions to build configs that
I use day to day. Eventually configurations should trigger builds though, just
like the nixos configuration system does. The DOSBox bit was in there because I
made a goal for myself to make something that was usable from DOS soley through
the VFS as proof-of-concept, but I have no intentions of making the DOS package
collection :)

I meant that in theory you could generate a derivation in the process of
generating a derivation, this is not possible with the Linux implementation
because of a few different issues. This is a pretty abstract issue that only
comes up rarely, I probably shouldn't have mentioned it without backing up
the claim.

Yes, that would probably happen the same way as in nix-pkgs, with a meta attribute
attached to packages, when there is a wrapper over the Genode build system, there
will probably just be a little snippet on the entry function that would add the
Genode license to components. By documentation I just meant some informal stuff.

Cheers,
