Title:
  Unmounting fails for local builds

Status in livecd-rootfs package in Ubuntu:
  New

Bug description:
  livecd-rootfs creates non-private mounts. When building locally using
  the auto/build script unmounting fails.

  To unmount dev/pts it is insufficient to make the mount private. Its 
  parents must be private too.

  Please, change teardown_mountpoint() accordingly. Patch appended.
