SUSE Linux Enterprise Desktop (SLED), formerly introduced as Novell Linux Desktop, is a Linux distribution supplied by SUSE and targeted at the business market. It is targeted for desktops. New major versions are released at an interval of 24–36 months, while minor versions (called service packs) are released every 9–12 months. SUSE Linux Enterprise products, including SUSE Linux Enterprise Desktop, receive much more intense testing than the openSUSE community product, with the intention that only mature, stable versions of the included components will make it through to the released enterprise product.
