With a couple of guys we've been discussing a slightly
backward-incompatible change in the way how fmf is handling the root
of the metadata tree. In short we suggest to clearly define where the
metadata tree starts by including an ".fmf" directory:
This approach is very similar to what git does and should allow us to
request metadata from inside the directory structure without always
having to specify the root. If you have any concerns or suggestions
regarding this change, please join our discussion on GitHub.
