## This is a maintenance script used to bootstrap the nodes from
## Nitos testbed (NITLab) before running a OMF experiment using
## Nitos nodes. This fixes the problem of Resource Controller
## misbehaving by restarting it and it also loads the ath5k driver.
# Example of how to run this experiment (replace with your information):
#
# $ cd
# python examples/linux/nitos_testbed_bootstrap.py -H -u -i -g -U
#
