Ubuntu Grub2 does not pick up Fedora volumes

[Jeffrey Walton]

Ubuntu 12's Grub2 does not pick up Fedora 17 volumes. Fedora is more cordial - it includes Ubunutu. Other volmes (Linux Mint and Windows Vista) are found.

I was trying to maintain a configuration where Fedora managed Grub2. It appears the last Ubuntu kernel update snuck in an update-grub2, which lost the menu entry.

Not being a Grub expert, this becomes painful.
