# Start up a batch of linux sessions ready for testing. |
|
# There are a number of ways of starting up vmlinux to force a particular IP |
# address to be used, which are specified by the first argument |
|
# DHCP - Linux will get an IP address via DHCP. In this case we must poll |
# the router to get the newly created IP address. |
|
# STATIC - We force Linux to chose a static address, by an explicit ifconfig |
# in the etc/init.d/rcS of the initramfs. We need to select an IP |
# address that is not currently being used. |
|
# In both cases, potentially we get in a mess if someone else is starting up |
# sessions at this time. |

# If we are doing STATIC startup, the <count> must be followed by <count> IP |
# addresses. |
