   3 # This is an init script for openprotium for storcenter
   4 #
   5 # This script cleansup after a successful uboot based reflash.
   6 # A uboot reflash is done by changing the bootloader boot command
   7 # to tftp a flash image and flash the firmware. However the boot command
   8 # is never reset back to a regular boot. This way if the flash did
   9 # not work the next power cycle will cause another reflash. A nice
  10 # development recovery feature. So this boot script is the mechanism
  11 # to reset the uboot boot command. Once booted and access it validated
  12 # this script will issue command to reset the boot command.
  13 #
  14 # This command only has a start so stop is not necessary and should
  15 # as late in the boot process as possible to ensure a successful reboot
  16 #
  17 # Copy it to /etc/init.d/flashclean and type
  18 #       update-rc.d flashclean start 99 5
