I think the process as we know it was: Granato fired. After an extensive interview/search, Adams was set to promote Appert to HC. Terry managed to convince Ruff to join as HC. Ruff had to keep the staff because they were under contract and Adams ensured Appert was added to the staff. This would allow Appert to apprentice with one of the winningest coaches in NHL history.
The Sabrespace conjecture is that if Adams still has any decision-making power at the end of this season, he'll again do a very thorough set of interviews and then hire Appert as HC. Only a GM with some authority will be able to execute a real search.
