[Bug 1050774] Re: os-prober misparses GRUB 2.00 configuration, leading to arbitrarily-long grub.cfg output lines

[Launchpad Bug Tracker]

This bug was fixed in the package os-prober - 1.56ubuntu1

---------------
os-prober (1.56ubuntu1) quantal; urgency=low

  * Resynchronise with Debian (LP: #1050774).  Remaining changes:
    - Mount btrfs subvolume @ when present to access a btrfs formatted
      rootfs.
    - When called with WINOSDATA, return the list of Windows partitions
      containing the system instead of only listing these containing the
      bootrecord.

os-prober (1.56) unstable; urgency=low

  [ Hedayat Vatankhah ]
  * Add support for probing Fedora's location for the GRUB 2 configuration
    file (closes: #674560).

  [ Colin Watson ]
  * Fix the parsing code in the grub2 handler so that it no longer gets
    hopelessly confused by multiple single-quoted strings on the same line,
    as produced by GRUB 2.00.

os-prober (1.55) unstable; urgency=low

  * Improve detection of Haiku: detect the 64-bit version
    Closes: #685228
  * Add myself to Uploaders

  that ubuntu quantal i386 have been previously upgraded with this
