When using iscsi for example, an interface name (usually eth#) is

It's worth talking to Prarit about this stuff because he's looking into
persistent network device naming issues in general. I'm sure you know,
but there's a generic DMI extension that allows you to determine from
the system what the PCI slot->device name mapping should be so that e.g.
moving the disk from one system to another doesn't affect the naming.
Of course this only works on systems with the requisite SMBUS/DMI
extension *but* it will (eventually) be a nice solution to the naming
issues and worth working with him on if you're not already.
Hmm, well I really want to have something in place soon, and currently
all Fedora persistent network device naming is done based on MAC.
But I would like to keep possibilities like this open for the future, so
I'll go ahead and implement Seewer's suggeston to use a separate cmdline
arg for this called ifname, for now we will then have / use:
ifname=eth0:aa:bb:cc:dd:ee:ff
But in the future it could also be something like for example:
ifname=eth0:/sys/devices/bus/pci/00:00:00:01.5

Hans
