The GNOME Volume Manager monitors volume-related events and responds with
user-specified policy. The GNOME Volume Manager can automount hot-plugged
drives, automount inserted removable media, autorun programs, automatically
play audio CDs and video DVDs, and automatically import photos from a digital
camera. The GNOME Volume Manager does this entirely in user-space and without
polling.
The GNOME Voume Manager sits at the top end of a larger picture that aims to
integrate the Linux system from the kernel on up through the desktop and its
applications.
