Hi Emery,

thanks a lot for sharing your plans!

I am actually thinking in a similar direction but looking at the
problem from the "desktop" perspective. Technically, I don't see a
component as an ELF executable. I think that we will need to define
some kind of container format with a standardized structure. The
content of such archive could be inspected by a management component
(e.g., "desktop") to configure and dynamically integrate the component
into the Genode system. The archive should contain meta data such as a
formal description of the component configuration like you have in
mind, the type of the component, the dependencies from other
components as well as the component's binary (or even more than one
binary such as shared libraries) and other data.

Very cool!

I hope that throughout the year, we will learn what a "distribution"
actually means in the context of Genode. Right now, I still fail to
get a grip on it.

Perfect sense. :-)
