"The software distribution system that works differently.
rootz mounts complete live distros over the web, and make them available locally.
Attach your local linux system to various mirrors and simply
run applications, without any installation or prior downloads!
* No special repackaging is needed (as opposed to klik, zero install or autopackage).
* True "on demand" mechanism that does not require full download of the software but fetches only the needed files.
* Support multiple mixed images - run experimental apps from debian sid side by side with ubuntu stable app, fedora, mepis and more.
* Secured - unchanged, isolated (chrooted) images."
