- Device names are made from their physical addresses. So like the dec tulip driver
will create a name like dectulip_0_10, meaning the card plugged in pci bus 0, device
number 10. If you move the card, the name changes. BUT, if you stick in another
ethernet card, the old one retains its name. If you want, it also creates alias names,
like _ether2, _ether3, etc., sequentially numbered that you can use as well.
- Directory names must have the trailing slash appended. So specify ../startup/ to
reference the startup directory.
- All images to be run must be in directories pointed to by the OZ_IMAGE_DIR logical name
(just like the PATH envar in unix).
