grub2 is not the future. Grub2 is an unfortunate accident on the way.
That said much of the problem being experienced is because Fedora 16
wasn't properly tested and instead of fixing their grub2 configuration
and migration they totally screwed it up and left boxes unbootable.

That was *crap*.

On a box with insufficient space they should have given the user the
choice of grub1 or telling grub2 to install itself using a map file
(which is *exactly* how grub1 works).

You don't need a bigger reserved boot space. That's a Fedora screwup.
Tell Grub2 to use a map file.

Would have been easier if Fedora 16 had offered the use of map files. The
grub2 people covered this but Fedora blew it, just like the 10,000 lines
of garbage that break and mash your grub2 config are a total failure.

Fortunately grub2 is not the future. On an EFI system with Matt Fleming's
work you can boot a kernel direct from the firmware.
