[Bug 446764] Re: os-prober should chainload other linux if there is bootloader on the partition

[David]

I forgot to attach the file that should be installed in /usr/lib/os-
probes/mounted/89grub

It returns "grub" as detected OS and it is parsed later in /etc/grub.d
/30_os-prober

Title:
  os-prober should chainload other linux if there is bootloader on the
  partition

Status in “os-prober” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: os-prober

  I have two Linux distributions installed.  SUSE prefers to install
  it's bootloader on it's root partition rather than on the MBR.
  Ideally os-prober / grub-common would see that the partition has a
  bootloader (grub) on it and chainload instead of loading the other
  distro's kernel directly.

  This approach would be a lot safer than the current approach because
  it would allow the other distro to fully control the kernel parameters
  used to boot and would (assuming the distro takes care of this itself)
  allow the other distro to upgrade it's kernel or change parameters
  without os-prober needing to re-detect.
