I think you'd want
ifconfig | grep ether | head -1 | sha256 | md5
otherwise you are reliant on *none* of the ethernet cards changing
rather than just the first not changing.
Also s/never/rarely/. I don't change my ethernet cards every day, but
every once in a while it will happen. But I would have said that was
good enough.
