The included script creates a disk image with the packages needed to offer some basic functionality and load the users filesystem, and install gcc and its shared libraries.

If it's not given a USERS parameter pointing to a usersfs partition on boot time, it boots to a Node.js REPL prompt. To fill the disk image without sudo it's needed to use genext2fs. You can install it on Ubuntu by executing:

  sudo apt-get install genext2fs

NodeOS is incredibly lean, leaving most of the system configuration up to the installed packages.
