Right.

Scott, can you check if any of the manuals mention LINUX_VERSION
without overrides such as LINUX_VERSION_minnow. If there is any that 
need to be changed.
  I am noticing that the reference manual, and BSP guide both need this change.

Bruce,
  This file should change too:
   meta-skeleton/recipes-kernel/linux/linux-yocto-custom.bb

Thanks,
Nitin
