Title:
  Desktop LiveCD install erroneously "requires" NewWorld boot partition
  (and/or Yaboot) on Pegasos PPC

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: base-installer

  * Boot Edgy Desktop CD on a Genesi Pegasos or ODW
  (you will need a vmlinuz-chrp.initrd kernel for this; see http://www.ppczone.org/ - also remove the BusID and UseFBDev lines from /etc/X11/xorg.conf once it fails, and "startx" to hit the installer. Other bugs reported for those)

  * Run through the installer until you get to "Prepare mount points"

  You cannot click Forward from this point. Genesi recommends using the
  RigidDiskBlock (Amiga) or MBR parititoning schemes as the Firmware
  understands these and they are most relevant to Linux. Neither of them
  are supported in the LiveCD, although manually partitioning using
  Alternative works just fine.

  You do not need Yaboot if you can install a CHRP initrd kernel using
  mkvmlinuz.

  Proposed fixes:

  * Detect Pegasos (it's fairly easy using info in /proc/device-tree)
  * Provide "mkvmlinuz" on install CD
  * Set boot loader to "mkvmlinuz"
  * Get rid of that warning if Yaboot isn't the required bootloader, and allow installation to proceed.
