You can put that sleep in the hostname.trunk file using "!sleep 10". It's not uncommon to use a sleep to wait for layer 2 protocols to settle. I sometimes use a sleep on the "last" physical interface if any of the interfaces are connected to a switch where spanning tree has to enable forwarding on the port. This prevents carp problems where the booted system becomes master for a while, because the link is up but the carp traffic is not forwarded yet. -- Cam
