What i don't understand is why didn't they just update it, by adding the same functionality to legacy grub?
What I mean by that is, was the scripting language absolutely necessary to add that additional functionality in grub2? From what i've read about/ know about GRUB legacy and GRUB2 are that the only real significant changes are that instead of updating grub manually, GRUB2 can be updated automatically. It still doesn't prevent users from still having to manually add or edit the custom list to add OS's if they aren't recognized on the initial update or configuration.
Which literally mean this:
Red Hat Users:Code:
su gedit /boot/grub/menu.lstCode:
sudo gedit /boot/grub/menu.lst

Grub 2 also supports UUIDs which is better for booting external disks and non x86 type architectures. I read somewhere (that I can't find now) that the original grub code had become a tangled mass of spaghetti which was hard to maintain. I have no idea how accurate that article was.
It's not that difficult to configure.
/etc/default/grub is a text file with your configuration variables
/etc/grub.d is a folder that holds a file for each menu entry. The files will start with a number that indicates the order they appear on the menu. They do look overly complicated when compared to menu.lst. Fortunately, I've never needed to edit one They can be enabled / disabled simply by marking them executable or not.
and of course update-grub sorts everything out.
Having said all that, it was definitely easier to manually configure grub so on that basis alone I would have to say that the original grub was better ^_^

Information on grub can be found here. The configuration for grub2 can be quite straight forward see here.
I somethimes use the config files and update-grub and sometime manually modify menu information (actually copy information into /etc/grub.d/41_custom and use update-grub). Grub2 took a bit more getting used to than grub legacy but then there are a few more features available. At the time I switches to ext4 grub legacy did not support boot from ext4 so I started using grub2, otherwise I would probably have stuck with grub legacy
