** Description changed: In Ubuntu, we clear /tmp on every boot. As such, on servers, by default /tmp should actually be a tmpfs entirely in RAM. This has several advantages, mainly: - * Performance - much faster read/write access to data in /tmp - * Security - sensitive data would be cleared from memory on boot, rather than written (leaked) to disk -- important for encryption scenarios + * Performance - much faster read/write access to data in /tmp + * Security - sensitive data would be cleared from memory on boot, rather than written (leaked) to disk -- important for encryption scenarios + * Power consumption - storing information in memory is more energy efficient than reading and writing to disk
