Public bug reported:
Binary package hint: os-prober
When Natty has to update-grub, it always fails to detect my Maverick
installation on another partition. This problem started about two weeks
ago, prior installations of Natty detected the Maverick partition,
correctly. Today, I did a fresh Natty install from the Nov-30 alternate
ISO image and was able to find the following in the installer syslog:

Maverick is on sda2 and, for some reason, os-prober is unable to access
it.
Release is Natty 11.04. os-prober is 1.41. grub is
1.99-20101126-1ubuntu2.
Whenever I install Natty or install a Natty kernel update, grub2 loses
the ability to boot to Maverick. To workaround, I have to run the
Maverick Live CD and manually grub-install. The Maverick grub2 and os-
prober correctly configure both my Maverick and Natty partitions.
