My recollection was that git doesn't ship with ebuild metadata by default,
so even if we make the first sync fast (by using depth=1 in the clone) do
we have a good story for ebuild metadata? Is portage just faster than in
the past for ebuilds with missing metadata? Does emerge --sync handle
metadata regen for syncs with git origins?
