#These script can be placed into the following file and then written to memory.
#
###Code:
###
###/etc/persistent/rc.poststart
#
#Remember if the script isn't quite correct it may brick the radio to a point
#where you'll need to perform the full reset procedure. We normally run the
#script manually first which will apply the changes without making them
#permanent.
#To commit the changes to the radio type the following and reset...
#
###Code:
###
###cfgmtd -w -p /etc/
