Hi all,

I'm trying to undersand how udev and configuration of network
interfaces work together. I read a few articles explaining how udev
works, how to define rules, ... but, having a look at for instance a
SuSe 9.3 configuration, there are two things that are not clear to me:
1 - I understand that they are udev rules defining the naming
convention used to create something like
ifcfg-eth-id-00:12:79:d5:9e:25 in /etc/sysconfig/network/ but I don't
really understand how this file is "connected" to, for instance, eth0.
It was my understanding that rules placed in /etc/udev/rules.d would
have made the trick but I had a look there and see nothing related to
eth0. Where/how is it define that what you see with an ifconfig
corresponds to what is written in ifcfg-eth-id-00:12:79:d5:9e:25?

2 - I was my understanding that the use of udev would have allowed a
really "slim" /dev folder but when I look at /dev, I still see the
hundred of devices I used to see on kernel 2.4 - based distribution??

I've no problem, just curiosity but any hint/explanation would be
appreciated :-)

Hiya!
I'm not sure I see what you're looking for, but if it's the naming of the NIC's, it's made in /etc/udev/rules.d/30-net_persistent_names.rules

Like in one of my boxes, there's a line:

SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:0c:29:54:a6:44", IMPORT="/lib/udev/rename_netiface %k eth0"

That in short renames "00:0c:29:54:a6:44" to "eth0" for simple use.
