Instead it simply puts each unpacked archive into its own directory. By contrast, when 0install installs (caches) a package, it does not run any code from the pacakge and it does not write to any of the traditional software directories like /usr/bin or /usr/lib.

Even if they didn't, the fact that the package can unpack files to directories such as /usr/bin or /usr/lib effectively gives them root access anyway. When installing a package, most installation systems execute pre- and post-install scripts inside the package as root, giving the package full access to your machine.If you have already installed a package using your distribution's installer then 0install can use that instead of downloading a second copy.Binary and source packages - supports both compiling applications from source and downloading binaries.0install supports sharing of binaries (the implementation cache) between users and between virtual machines.Conflict free - if two programs want the same version of a library, they'll share it.Decentralised anyone can distribute software.It supports both binary and source packages, and works on Linux, Mac OS X, Unix and Windows systems.
