These install are all based on wheezy. And I failed to note above, that
if a new machine gets that drive, this must be reset with the dmesg
discovery data:
0x14e4:/sys/devices/pci0000:00/0000:00:1c.4/0000:03:00.0 (tg3)
And it might be potentially useful to be using the same MAC address, but
to be pure, that should also be obtained from dmesg. That depends on
how persnickety the rest of ones local network is about it. dhcp comes
to mind as a potential problem child, but thats one daemon that never
gets started anyplace but my router. YMMV.
