Title:
  [PATCH] Add support for booting from subdirectory in root

Status in “initramfs-tools” package in Ubuntu:
  Confirmed

Bug description:
  Attached patch allows booting from some subdirectory on root
  device via "rootsubdir" command line parameter. It is very similiar
  to booting from loop device, except it uses "mount -o bind".

  This is useful for devices whose main OS is not Ubuntu - e.g. android
  devices like Nexus 7. Ubuntu then does not have to
  replace Android, and can be easily dual-booted.

  Note: this patch can't handle paths with spaces, and I don't know how
  should that be fixed. Anything with spaces should not be even passed as
  kernel parameter I guess. Anyway, the "loop" option has the same problem,
  since rootsubdir does almost the same thing.
