Re: The magical mystical changing ethernet interface order

Hello Ray & All , While that RedHat/Debian/... have figured
these out is really nice . NOT one of those methods appears to be
available for hand built distros . Ie: there does not appear to
be a standardised(tm) method to approach this difficulty through
out all drivers (not just ethernet) .

Could someone please point me to NON RedHat/Debian/... centric
tool to determine the proper ethernet for now ?

Modules are not an option for me here . Imo: If this can be done
with modules it should well be possible for staticly built
drivers as well . Tia , JimL
