It works, but I think it worked also before.
The problem is that change in naming interface is not good.
That's right. But the initscripts fixes the apparently random
reassignment that people are seeing. It has to pick an order, and if that
wasn't the last one you saw, it will change. From now on, though, it
won't change any more.
I don't think it's apparently random.
It is definitely after some driver in the kernel makes hardware
recognized.
It is definitely related to the order of detection, but that's not
entirely predictable. For example, before updating initscripts, I'd see
the order of detection change over the course of several rapid reboots
with the same kernel. The various workarounds suggested (and some others)
would affect the relative frequencies of the orderings, but none would
guarantee a single ordering.
For example, if I remove both the bcm43xx and sis900 modules, and load
first the sis900 and after the bcm43xx the order return that I want
(eth0 lan and eth1 wireless).
And after kernel upgrade I see always the same order, first the bcm and
after the sis, so eth0 is wireless and eth0 is the lan.
So, question are:
1. Is possible to make unloadable at boot a module?
2. Where info about names are stored? There is a file, or is only at
runtime (on boot or modules load)?
3. Is blacklist file in /etc/modules.d used to make modules unloadable
at boot time?
Not sure of the answers to these questions. It is possible to force
modules to be inserted in a particular order, in theory. For example, in
/etc/modules.conf, I had at one point:
install ipw2200 /sbin/modprobe -q eth0; /sbin/modprobe --ignore-install ipw2200
That would force eth0 (e1000) to load before ipw2200. Unfortunately, it
didn't always work before the initscripts fix. I haven't checked after
updating initscripts, because I'm getting the order I want.
