What was missing here is the mapping between our booting SCSI bus number
...
and the parent (hba) path from which we booted from. As a temp fix,
we'll only go with the first match to set altbootdev- not additional matches.
The problem was further exacerbated by the fact that cnpoll doesn't seem
to work on serial consoles.
