This raises an interesting question to me.
Is there a way to patch up a version "3.9" kickstart image that could be blizkicked to directly?
Kinda what Kickflash does, but using the blizkick util, and still needing a single reboot....?
Would that give full 3.9 support, with only needing the same memory allocation as a single blizkick'd 3.1?
