A little advance planning would be good here.  You are preparing to
play Russian roulette with more than one loaded chamber.

1. You need a backup system

2. Harddrives are cheap.  Get an extra, if needed.  Here's Collins'
almost foolproof way of doing maintenance.

	a. Create an extra partition (or 2 if you are using a /boot
partition).
	b. Clone your existing, working distro to the new partition(s).  If
you like, 
	    I can send you my simple shell script which you can modify for
your
	    root fs structure.  After cloning, modify the new partion's fstab
to match.
	c. Create a Lilo/grub stanza to boot the new partition(s).  Update
Lilo, if
	    using Lilo.
	d. Verify that the new system will boot and run.
	e. Create or update a Lilo/grub boot disk and verify that this will
boot
	    everything you need.
	f. Do your maintenance, or install a new distro, or whatever.  With a

	    new distro, decline the option to install a boot manager.  Do
that job
	    manually.
	g. If you roll snakeyes, you know how to recover.

Enjoy,
