升級 mysql-server-5.0 遇到的問題！

[ericsson]

系統：debian 2.4.27-2-386

各位好，目前個人的主機是使用 stable ，但是日前想要將 mysql 升級至 5.0 ，因此，將 sources.list 修改為
deb http://ftp.tw.debian.org/debian/ testing main
deb-src http://ftp.tw.debian.org/debian/ testing main
deb http://security.debian.org/ stable/updates main

更改完畢之後，執行 apt-get update 與 apt-get install mysql-server-5.0
以下為安裝的部份紀錄

You are running a kernel (version 2.4.27-2-386) and attempting to remove
the same version. This is a potentially disastrous action. Not only
will /boot/vmlinuz-2.4.27-2-386 be removed, making it impossible to boot
it, (you will have to take action to change your boot loader to boot
a new kernel), it will also remove all modules under the directory
/lib/modules/2.4.27-2-386. Just having a copy of the kernel image is not
enough, you will have to replace the modules too.

I repeat, this is very dangerous. If at all in doubt, answer
no. If you know exactly what you are doing, and are prepared to
hose your system, then answer Yes.

Name Service Switch update in the C Library: pre-installation question.

Running services and programs that are using NSS need to be restarted,
otherwise they might not be able to do lookup or authentication any more.
The installation process is able to restart some services (such as ssh or
telnetd), but other programs cannot be restarted automatically. One such
program that needs manual stopping and restart after the glibc upgrade by
yourself is xdm - because automatic restart might disconnect your active
X11 sessions.

Known packages that need to be stopped before the glibc upgrade are:
xdm kdm gdm postgresql xscreensaver

This script did not detect any installed services which need to be
stopped.

If you want to interrupt the upgrade now and continue later, please
answer No to the question below.

Name Service Switch update in the C Library: post-installation question.

Running services and programs that are using NSS need to be restarted,
otherwise they might not be able to do lookup or authentication any more
(for services such as ssh, this can affect your ability to login).
Note: restarting sshd/telnetd should not affect any existing connections.

The services detected are:
atd inetd webmin proftpd apache snmpd lpd postfix cron ssh

If other services have begun to fail mysteriously after this upgrade, it is
probably necessary to restart them too. We recommend you to reboot your
machine after the upgrade to avoid the NSS related trouble.

想要請教各位的是，在更新至 mysql-server-5.0 ，這樣子的更新讓我覺得不是很安全，雖然最後更新成功了，但是卻是有部份的錯誤訊息需要解決....我了解系統最好不要在 stable 和 testing 之間相互安裝，但是如果我的確需要 testing 中的軟體，什麼樣子的執行步驟才是正確的呢？

此外，我不是很能夠理解的是為甚麼在更新 mysql ，但是卻要移除 kernel-image，甚至包含目前正在使用的 kernel-image？
不知是否可以請各位指教，謝謝您！
