Title:
  *BSD not detected by os-prober

Status in Bootloader Manager for Ubuntu:
  Invalid
Status in “os-prober” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: os-prober

  I have a multiboot system with Windows XP, Ubuntu 9.10 alpha, and
  FreeBSD 7.2 installed. After Karmic Alpha-4 (upgrading with apt-get up
  to the time of the bug report) installing with Grub 2 in the MBR, the
  FreeBSD partition is not recognized.

  Some system information:
  DISTRIB_ID=Ubuntu
  DISTRIB_RELEASE=9.10
  DISTRIB_CODENAME=karmic
  DISTRIB_DESCRIPTION="Ubuntu karmic (development branch)"
  Linux lightning 2.6.31-10-generic #34-Ubuntu SMP Wed Sep 16 00:23:19 UTC 2009 i686 GNU/Linux
  model name	: VIA Samuel 2
  cpu MHz		: 798.000

  General disk layout:

  /dev/sda1 - Windows XP
  /dev/sda2 - Ubuntu /boot partition
  /dev/sda3 -  FreeBSD 'slice' containing all BSD partitions
  /dev/sda4 - subdivided into remaining partitions for Ubuntu

  Previously (with Ubuntu 9.04 and Grub 1) the booting worked well for
  all 3 OSes.

  There is an old Windows 95 drive on /dev/sdb - the OS on that is
  detected by os-prober. Currently, running os-prober gives me the
  results:

  root at lightning:~# os-prober
  /dev/sda1:Microsoft Windows XP Professional:Windows:chain
  /dev/sdb1:Windows NT/2000/XP:Windows1:chain
  root at lightning:~# 

  On a similar system runing XP, Ubuntu 9.04, and FreeBSD, the (Grub 1)
  menu.lst stanza for FreeBSD 7.1 is

  # Choice 0: use 1st BSD subpartition in disk 1 partition 3
  title FreeBSD 7.1
    root (hd0,2,a)
    kernel /boot/loader
