I had the following scripts in my rc.local:

io-net -d speedo -p tcpip
waitfor /dev/io-net/en0
mount -T io-net /lib/dll/npm-qnet-compat.so bind=en0
ifconfig en0 *.*.*.*


But when the target started, it gave me the following error:
Unable to init dll devn-speedo: Resource busy
...

But after logged in, i retried "io-net -d speedo -p tcpip", no problem then.

thx
