Bug#488267: lenny-beta2-netinst: wifi interface renaming causes big glitch on first reboot
Otavio Salvador wrote:
Hello Barry,
Looking at the output data I fail to see how this mess happened. I'd
like to ask you to do another test for us. Please boot d-i and after
wireless has been properly setup grab the following information:
/proc/net/dev
lspci -knn
My current bet is that wireless is using a different module, but it's
a guess and I'd like to confirm that.
Hi Otavio!
Thanks for your emails. I'm delighted my installation report is being
taken seriously, and I'm very happy to try to help out. It was a great
day for me when the d-i started to support wifi devices for netinstall
(unlike ubuntu still, I think!) because my ethernet sockets are in
awkward places and wifi is so much easier especially for laptops. So
I'm happy to try to help make this easy for others too.
I shall be particularly glad if we can get to understand this ifrename
stuff. It has plagued me before (mainly with PCMCIA wifi cards) but is
just easy enough to work around that there's little incentive to find
the real mend. I always had a suspicion that it was udev (don't you
just love and hate udev?) and it does seem to play a role, even if not
the main role (see syslog extract below).
Anyway, here's the info you asked for, followed by some you didn't.

(sorry, wasn't sure whether to send you the complete lsmod, but just in
case).
Finally, here are the amazing (to me) lines in syslog on (currently)
booting the installed system, each group being consecutive lines: I
don't think I've omitted anything relevant, but I could send you more if
you want. There was no cable plugged into the ethernet eth0. Note the
line where udev "renames" wifi0 to eth1:
(no previous mention of eth1, wlan nor wifi)

I hope you can make something of this. I'm still at a loss to
understand where wlan0 gets renamed to wlan0_rename and "by whom" - it
does seem to be some part of the kernel, rather than userspace (?).
Let me know if you'd like me to try anything else. I'm a bit busy today
(Sat 28th June), so I won't be able to try the daily image (for the
firewire CD bit) till at least tomorrow, sorry.
Best wishes,
Barry
