I believe the problem is much deeper than that and while your observations are valid, you don't have a root cause yet. You just have a happy symptom that works with your specific configuration. Here's what I've found after much up & down-grading and rebooting: First, I've had netmount in the default runlevel for ages and it's worked for ages even though it does nothing. Second, openrc has been launching "dhcpcd -q" at boot time for ages and this has never interfered with wicd which comes along later. openrc-0.8.* always works with any kernel version openrc-0.9* work with kernel-3.2.5 openrc-0.9* does not work with kernel-3.2.6, giving these errors: Feb 26 17:16:53 khamul dhcpcd[2661]: wlan0: leased 172.20.0.41 for 43200 seconds Feb 26 17:16:53 khamul avahi-daemon[2479]: Joining mDNS multicast group on interface wlan0.IPv4 with address 172.20.0.41.

I'd say the root cause is a change in kernel-3.2.6 that was not tested against. So, what's the next debugging step? -- Alan McKinnnon alan.mckin...@gmail.com
