I agree, the consistency is well worth it.

With Debian hat on: we should have a conversation with Vagrant WRT the
planned u-boot version for Jessie. v2014.10 should be available before
the freeze in November so hopefully we can go with that for Jessie, but
if not then perhaps we can backport some minimal set of patches so that
at least the env names match even if we don't manage to get the full
updated default env.
