<blockquote>We already have Install/Uninstall scripts for packages. You invoke them when you
do a yum
install or a apt-get install to install the software then apt-get remove and yum remove when
you remove the software.</blockquote>
Currently these scripts are minimal and are written by people who actually know what they are
doing WRT distribution integration, etc.
You have only to look at the incredibly complex and unreliable scripts shipped by Plesk,
VMWare, etc. to see what kind of horrors such a system would unleash on our users.
