[SHR-Testing] /etc/network/interfaces edit question

[arne anka]

since you started a new thread w/o sufficiently quoting or explaining your  
issue, i am not sure, if the name you _have_ is wlan0 or ethX (where X !=  
0).
in either case my first attempt would be to grep through /etc/udev/ for  
the static part (ie wlan or eth):

grep -r wlan /etc/udev/

and if something turnes up to have a lokk at the line in question.
f ex the rule mentioned reads

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",  
ATTR{address}=="00:1a:a0:a0:f8:18", ATTR{type}=="1", KERNEL=="eth*",  
NAME="eth0"

ATTR(address) denotes the mac address.
