Hi,

In light of our IRC chat in #d-ftp today and the asumption that the
"Only-Extra-Source" field will be implemented, I believe I have a
trivial patch that will work[1].  There is an updated test for it in the
"britney2-tests"[2] (the new repository announced today - not the old one).
  The patch is backwards compatible and could be applied before the
extra sources appear in the Sources files (and without updating any of
the unrelated existing tests).

It is my understanding that the new field has only been proposed at this
point, but the field would greatly simplify the Britney changes and keep
the risks of regressions at a minimal.
