"The latest Webconverger 15 release is the first Linux distribution to be automagically updatable from a Github repository. The chroot of the OS is kept natively in git's format and fuse mounted with git-fs. Webconverger fulfills the Web kiosk use case, using Firefox and competes indirectly with Google Chrome OS. Chrome OS also has an autoupdate feature, however not as powerful, unified & transparent as when simply using git."
