Debian Live is an open source Live CD flavor of the well known Debian GNU/Linux operating system.
The Debian Live project is splitted into five different editions, each one containing a popular, open source desktop environment, such as KDE, GNOME, Xfce and LXDE.
There are two installers provided on the Live CDs, a text mode and a graphical one.
Besides some standard command-line utilities, this edition does not come with any other applications.
All in all, Debian Live Standard Edition is a very good starting point for creating your own Debian GNU/Linux operating system, just the way you like it!
