1 Here's a marvelous program crying out for an ebuild;
5 It's part of my Ubuntu setup. With one click it goes out and finds all
6 the boot partitions on your hd(s) and automatically writes the proper
7 grub2 configuration for them. It even pastebins a copy of grub.cfg
8 for troubleshooting purposes, though I have never needed it, sof far.
9 When you boot all your OSes are there in the menu ready to be
10 selected. In my case Ubuntu, Gentoo and Sabayon. .
