Are you using Faronics Deep Freeze product to prevent users from adding to your IT helpdesk calls?  The product “freezes” the OS such that any changes (good or bad) being made to that computer (from say curious users or viruses) can easily be wiped out, and a clean OS state can be easily restored.  Used in places such as classrooms, labs, kiosks, or any other location with “at risk” devices.  Learn more about Deep Freeze here and here.

Formerly only available on Windows, the company announced that its Deep Freeze Linux product is now available.  It is currently only supported on SUSE Linux Enterprise Desktop.  Read the press release here (pdf).
