No, that's "ensemble upgrade-formula".  "ensemble upgrade" is about
upgrading the software itself.  Or, at least that's how we've been
referring to those issues.  This isn't settled in stone, but there are
two different problems here, and we have to handle them both.

Both approaches are "correct" as far as Ensemble is concerned, and
they'll both be supported.  Clint's approach is the only one supported
on official formulas.

More clearly: if you want a formula to be officially blessed as part
of _Ubuntu_, the software it manages must be part of Ubuntu.  For a
personal/company formula, anything is ok.
