The problem is more basic than that. mysql will not even start once the 7.0.0 packages are installed because conf/my.cnf is wrong (even though the installer says it verified my.cnf, it's not enough to get mysql to start).

Nothing I've tried upgrades the mysql data so that install.sh (the database check at the begging of install.sh succeeds).
