Problem Description
==============================
Unlike PowerKVM and Fedora 21, Ubuntu 14.10 adds boot images from other disks to it's grub config which makes the Petitboot menu very cluttered.
 
Machine Type = 8286-42A 

Steps to Reproduce
===============================
  Petitboot (dev.20150216)                                      8286-42A 107C53T

- I then installed Ubuntu 14.10 on a second drive:

Jeremy Kerr indicated that this is the fix:

GRUB_DISABLE_OS_PROBER=true 
In /etc/default/grub
