New Linux Package - Grub's Menu.lst changed. What do I need to change back?

This is a question regarding this HowTo:

How To Set Up Software RAID1 On A Running System (Incl. GRUB Configuration) (Debian Etch)

I've set up my system using this HowTo, and it's running great. At boot up, I get a choice to boot from either hd0 or hd1:



Today, I got this Debian security update:

Package : linux-2.6
Vulnerability : several vulnerabilities
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2007-6694 CVE-2008-0007 CVE-2008-1294 CVE-2008-1375

Several local vulnerabilities have been discovered in the Linux kernel
that may lead to a denial of service or the execution of arbitrary
code. The Common Vulnerabilities and Exposures project identifies the
following problems:

So I do a "apt-get update" and "apt-get upgrade". After it has installed the new kernel image, it tells me to reboot which I do.

At reboot, I immediately noticed it has changed grub's menu.lst without creating a backup of my old menu.lst. So I change the menu.lst back to what it is supposed to be.

But is that the only I need to change/do after a new kernel image has been installed? Or do I need to do some other stuff too, perhaps a "update-initramfs -u"?

That should be all you need to do. IT should then boot your old kernel again using the old ramdisk.

[ClarkVent]

Well, I don't want to boot the old kernel, but the new.

What's in your menu.lst, and what's the output of

ls -la /boot

?
