My rule of thumb is that if I do not understand what a package is for or what a program does or why it is installed, I do not need it. So I would start by something like this. Say, I want to know about some service called exim4. The relevant file in this case is /etc/init.d/exim4. Let's see where it comes from rajulocal@hogwarts ~ % dpkg -S /etc/init.d/exim4 exim4-base: /etc/init.d/exim4 So it is coming from exim4-base package. Find out what the package is about. rajulocal@hogwarts ~ % apt-cache show exim4-base Looks like it is some mail transport agen program. Do I need it? If not let's try to remove that. rajulocal@hogwarts ~ % sudo apt-get remove --purge exim4-base Look at the dependencies it is trying to remove and understand what those packages are about. If none of them look interesting just remove it. If you want to make sure that the packages you remove do not interfere with KDE, make sure that kde-full is not removed as part of "apt-get remove --purge" and then you should be fine. raju -- Kamaraju S Kusumanchi http://malayamaarutham.blogspot.com/ -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
