# ATA Over Ethernet (AOE) start/stop scripts. 
# `service aoe start` will modprobe aoe
# `service aoe stop` will bring down all mounted aoe drives
# `service aoe status` will provide the status of AOE
#
# To install so aoe is automatically started/stopped with the machine:
# 1) Move this file to /etc/rc.d/init.d/aoe
# 2) Create a link to this file called /etc/rc.d/rc3.d/S11aoe
# 3) Create a link to this file called /etc/rc.d/rc0.d/K89aoe
# 4) Create a link to this file called /etc/rc.d/rc6.d/K89aoe
#
# NOTE: Steps 2-4 are configuring aoe to automatically start on Init 3 
# and get killed on Init 0 or Init 6. Change the numbers (S11, K89) as
# needed to make sure AOE starts -after- the network in rc3.d and is
# killed -before- the network in rc0.d and rc6.d
