Maybe if they all take the same driver they are probed in a fixed order.
Mine usually have a mix of at least broadcomm and intel. Also note
that once the NIC mac address is set as HWADDR= in the ifcfg-eth? file
the settings will stay fixed (with a weird scheme of renaming the device
after kernel detection...).

Clonezilla just copies your source, so the same thing happens as would
happen if you moved the original disk to a different chassis - which is
also a likely scenario for me. Kudzu will rename your ifcfg-eth? files
with a .bak extension and create new ones that default to dhcp. If
kudzu doesn't run and you have the wrong HWADDR= setting in the file the
interface won't come up at all.

This gets a lot harder when you've shipped the disk elsewhere for
installation and the operators there only know windows.

I think the bsd's have a mapping between the driver needed and the
device name. I don't really care what the name is, as long as I know
the names that correspond to the physical jacks and they are consistent
across machines with the same bus/card layout.
