Refining installation of ipc has enabled me to make some serious shortcuts. You may need to refer to my other ipc posts to fully understand this procedure.

• run the ipc diskimage from spare targetting an empty partition and choosing my standard settings
• use UInstaller to
  • apply AppleYukon2.kext
  • apply ethernet and graphics string
  • apply IONetworkingFamily.kext (1.6.0)
  • apply IOAHCIFamily.kext

after these two operations I end up with a new bootable osx installation which takes < 10 mins to create.
