</blockquote><div><br>I have a couple of minor observations from the great unwashed - yes me. One is that this solution perhaps wont have any effect when one boots to the Gnome side. Two, this may be build version dependent, as there would appear from some of the discussions in the group that there is an effort for the 12.1.0 builds to more closely link the NM functions on Sugar and Gnome so that settings are identical when restarting the other environment. The echo script in boot startup and the corresponding entry powerd resume , on the other hand, might handle both. Not sure yet, as I'm still playing with WAP variants, and also, I am the newbie :-)<br>

</div>i think it's almost a guaranteed race. that script essentially<br>
does this:<br>
<br>
while [ ! -f /sys/class/net/eth0/lbs_mesh ]<br>
do<br>
sleep 0.5<br>
done<br>
echo 0 > /sys/class/net/eth0/lbs_mesh<br>
<br>
in other words -- the disable_mesh script will discover the disable<br>
node at just about exactly the time that NM discovers the interface.<br>
<br>
there's also the "lbs_disablemesh" module parameter, which could be<br>
supplied at initial module load. does that not work, for some reason?<br>
(i seem to recall there may be a problem with it.)<br>
