Thanks a lot for your help. I'm running Debian kernel version 2.4.27-2-386. I executed the command:
apt-get -y install apache2-mpm-prefork apache2-doc lynx php4 libapache2-mod-php4
Using -y, the only prompt I received was near the bottom of the output (see excerpt below), to which I answered 'No' when it asked whether I wanted to remove the kernel =:0
I haven't yet killed the apache2 processes, but do you know if the msgs below indicate a real problem?
Removing kernel-image-2.4.27-2-386 ...
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.
Remove the running kernel image (not recommended) [No]? No
dpkg: error processing kernel-image-2.4.27-2-386 (--remove):

dpkg: initrd-tools: dependency problems, but removing anyway as you request:
kernel-image-2.4.27-2-386 depends on initrd-tools (>= 0.1.48).
