Completely remove graphical package management interfaces?

[Niki Kovacs]

Hi,

I'm planning to install some Ubuntu 10.04 desktops in a SOHO 
environment. One of the things I usually do is uninstall strictly 
everything that's not needed by users.

Since my users are not supposed to install or remove software on the 
desktops, I thought I might as well remove every graphical frontend to 
that, e. g. Synaptic, the Software Center, the Update Manager and the 
likes. Installs and upgrades will only be performed by me, using 
dpkg/apt-get via ssh.

Can anyone of you more familiar than me with these more or less 
redundant interfaces give me a complete list of packages to uninstall in 
that case?

Thanks,

Niki
