Hi Boss,
So sorry to mail you in this rude way (if you look into this mail, I kn=
ow is
not support mail, but god guide missing people, right?=A0 )
I am finding a solution to my problem=85.
I have some machines with 8 net interfaces, I want to name one as eth0,=
I
need a solution to work for all machine ( I will clone OS from one to
others), so I could not just modify the rule file under /etc/udev/rules=
=2Ed=A0

I need setup a math condition works for all machine.=20
I want to change=A0 /lib/udev/rules.d/75-persistent-net-generator.rules=
file
to only match MACs
But my problem is that interface names turn out did not ordered by MACs=
,
It suppose=A0 00:0d:48:08:92:9a named as eth0, but not.

Is there any way to let interfaces named by MACs order?=20

You should avoid renaming devices to ethX, this is racy and especially
in recent udev versions it does not work.

You have two options:

1) Rename your devices to something not in the kernel namespace (e.g.,
lan0, lan1, ... or net0, net1, ...).

or

2) Use the predictable interface names, which is the default in recent
versions. This will give you a new set of names (see [0] for details).
