Need help with GRUB2: Setup for dual-boot with Arch

[fishin4guitars]

I'm thinking of dual-booting Ubuntu 10.10 and Arch Linux. It seems that I'll have to do some editing of the grub.cfg file, but I have seen numerous warnings not to do so. After a bit of poking around, I've heard about a script that does the editing for you built in to Linux (or maybe just Ubuntu).

My questions are:
- If the aforementioned script does exist, how do I use it?
- else if it doesn't exist, how do I not directly edit grub.cfg?

It is pointless editing grub.cfg as the next time grub is updated your changes will be over-written.
Which grub file you edit is governed by what you want to change about grub.
