Jose,
I don't disagree with this change, but can you please keep compatibility
with the old name for some time, as we have been using the "uninit_groups"
name for some time already.

I think we just need an additional stanza here after this one which has
the old name in it.  That way lookup-by-value will find uninit_bg, and
lookup-by-name will still work.
