All Linux distributions have things in common, but many differ in software installation and updating. Gentoo Linux is based on Portage, SUSE uses YaST, Red Hat and Fedora opt for yum, Linspire prefers CNR…. Oh, and don’t forget the different package options: RPM, Debian, source, and more esoteric options. Smart Package Manager works with all major distributions, replacing native tools and installing different types of packages.
