[Bug 530252] Re: os-prober fails to recognize linux installations with crypted root partition

[Julian Andres Klode]

So the context you miss is that os-prober runs each time update-grub
runs on the system still.

The use case here is a highly unusual setup where another OS is directly
installed to a LUKS partition instead of using LVM on top of LUKS, and
one needs to balance whether this is a feature we care about as Ubuntu
specifically or not, or whether this would be better addressed upstream.

Title:
  os-prober fails to recognize linux installations with crypted root
  partition

Status in os-prober package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: os-prober

  On Karmic, os-prober fails to recognize linux installations with LUKS
  crypted root partition (which is pretty common on laptops nowadays).

  linux-boot-prober at least finds partitions when they are luksOpen'ed,
  but /usr/lib/os-probes-mounted/90linux-distro doesn't even try to look
  at /dev/mapper partitions or to use linux-boot-prober.
