CentOS - Apr 2008 - sendmail and cups gets installed although not chosen in kickstart file

I setup a kickstart file that contains only @core and several packages 
explicitely listed. postfix is listed, sendmail is not. And there's no 
package where I would think it needs cups. Nevertheless, after the install 
I now have postfix *and* sendmail on the machine and sendmail even being 
enabled. And cups is installed.

How can I find out what forced them (and probably many other unwanted 
packages) on the installation?
I thought maybe "rpm -q --whatrequires sendmail" would tell me, but it
doesn't. Nothing requires it. Same for cups. So, why did it get installed?

I usually do a rpm -q --provides <package name> and have it list the
capabilities that the rpm provides and then do a --whatrequires on the
capabilities themselves. Hopefully someone more knowledgeable can jump
in and explain an easier way. But that is what I do. You'll see that one
of the items that sendmail provides is smptdaemon which is the usual
source of dependencies in my experience. However postfix also provides
it, so perhaps that's no help.

<assumption>
I would guess that sendmail is included in @core or something else is
that depends on a mail package. Just because you include postfix
later, you can't count on things included in @core that depend on a
mail program to know that postfix will eventually be there. I believe
sendmail is the default mail package when it comes to resolving
dependencies, unless postfix is already installed.
</assumption>

I have a work-in-progress kickstart config that attempts a more
minimal install than can be done from CD. The key is "--nobase". But
then many essential things must be explicitly installed. This gets me
postfix and no sendmail. YMMV.

%packages --nobase
bind-utils
coreutils
crontabs
dhclient
e2fsprogs
file
grub
mailx
man
openssh-clients
openssh-server
postfix
rootfiles
rpm
vim-minimal
vixie-cron
wget
yum
-kernel-smp

cups gets pulled in by the redhat-lsb package which has /usr/bin/lpr as
a requirement.

sendmail is in the core group. If you kickstart, you can say

-sendmail
postfix

in your package section to exclude sendmail from getting installed. You
don't want to exclude the redhat-lsb package, as that pulls in loads of
needed software during the installation.

It came in even after removing redhat-lsb. It stopped after using --
nobase.

I know that I can remove single packages, but I'm sure there were more 
unwanted packages getting pulled in. That's why I wanted to know more 
about the cause.

Thanks for the info. I checked the requires and I have most of them on the 
machine, anyway, probably from installing core. What's missing without 
redhat-lsb are a very few libraries like libICE. I'll see if adding 
redhat-lsb gives me cups again.
