* expanded to hold more than 2 devices (but then unit numbers, which
* don't currently exist, may come into play). If the device named by
* loaderdev isn't found, fall back using to the old "probe" loop.
*
* The original probe loop still effectively behaves as it always has:
* the first usable disk device is choosen, and a network device is used
* only if no disk device is found. The logic has been reworked so that
* it examines (and thus lists) every potential device along the way
