If I plug a USB-WLAN-key into my gentoo-box the service net.wlan0 is starting fine according my configuration. But when I remove the USB-WLAN-key the service net.wlan0 won't stop. Here is the message from the syslog: /etc/init.d/net.wlan0[11237]: ERROR: net.wlan0 failed to stop If I run the init script by hand via /etc/init.d/net.wlan0 -d stop the last lines of output are looking like this: + for module in '${MODULES}' ++ command -v dhclient_pre_stop + '[' '' = dhclient_pre_stop ']' + for module in '${MODULES}' ++ command -v vlan_pre_stop + '[' vlan_pre_stop = vlan_pre_stop ']' + vlan_pre_stop + local vlan= + _exists + grep -Eq '^[[:space:]]*wlan0:' /proc/net/dev + return 1 + exit 1 * ERROR: net.wlan0 failed to stop I assume the openrc module irpute2 is calling the function _exists() but it will return 1, because the network device (USB WLAN key) is not connected anymore to the computer. By the way, it is not an option to call /etc/init.d/net.wlan0 stop before removing the USB key. This machine is intended to act in a university practical exercise, where the students simply have to plug in and remove the WLAN USB key without any user interaction. The wireless network is a simple ad-hoc network with static ip adresses. Reproducible: Always Steps to Reproduce: 1. plug in the WLAN USB key 2. wait a until network is up 3. remove the WLAN USB key Actual Results: The network service (like net.wlan0) will not stop and produce the following message in the syslog: /etc/init.d/net.wlan0[11237]: ERROR: net.wlan0 failed to stop Expected Results: The service should stop even if the network device is not longer present. #

The problem seems to be gone with =sys-apps/openrc-0.9.8.4. After removing the WLAN-USB-Key the hotplugged service net.wlan0 went to state inactive. After adding the WLAN-USB-Key again the network gets configured as expected (like the first time).
