Title:
  Ubuntu creates cluttered Petitboot menu entries

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  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:
