I second this recommendation. While the MAC address in the manufacturing data may not be correct (if the WLAN card has been changed), it is guaranteed to be as unique as the laptop serial number. Using only the last three bytes of the MAC may not result in a unique name, however. It was when we only used cards from one manufacturer, but that changed starting with XO-1.5. My problem with the suggestions to randomly generate the host name are that no-one has proposed a method for detecting and correcting the name collisions that are sure to occur. (How is /dev/urandom seeded these days ?) Personally, most of the laptops I use don't have manufacturing data, but that can be corrected.
