# rc.local - BMC startup rc.local file
#
# This file replaces the default rc.local (or can be appended to it) to
# ensure the BMC daemon and serial console sesson start at boot and have
# the proper permissions for bmc.sh to work as expected. It also writes 
# some useful debug information to /var/log/rc.local.log should later boot
# analysis be needed.
#
# Has dependencies on the 'bmcd' and 'screen' utilities.
