Honestly, if Mohammad is dead set on doing an upgrade, I think he'd be
better of cooking up a bash script in a test environment that works
and using some sort of parallel-SSH to apply it.

There's just too many ways for a distro upgrade to go sideways in very
non-idempotent ways for a Chef run to be the right approach to do a
mass upgrade of the OS.
