add net-retriever/localrepo?

[Wouter Verhelst <wouter@debian.org>]

Hi,

I've been thinking it might be nice to extend net-retriever so it checks
the "net-retriever/localrepo" template. This would never be shown (only
used for preseeding), and would work similar to the "localudebs"
directory.

This could be used for more easily testing modules that aren't usually
included in a built image, but could also be used to allow people to ask
extra local questions in a mostly-preseeded environment, should they
want that (create the udeb, create the repository, and preseed
'net-retriever/localrepo" and "modules" to relevant values).

Thoughts?
