GoboLinux is an alternative Linux distribution which redefines the entire filesystem hierarchy.
In GoboLinux you don't need a package database because the filesystem is the database
What is GoboLinux?
GoboLinux is a modular Linux distribution: it organizes the programs in your system in a new, logical way. Instead of having parts of a program thrown at /usr/bin, other parts at /etc and yet more parts thrown at /usr/share/something/or/another,each program gets its own directory tree, keeping them all neatly separated and allowing you to see everything that's installed in the system and which files belong to which programs in a simple and obvious way.
GoboLinux is available as an ISO CD image. You can check out GoboLinux using this live CD, that contains a runnable system (with KDE, OpenOffice, etc) and an installation wizard.
