** 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. + in RAM, when there is enough memory in the system. This threshold + should be configurable by the end user (in cloud-init?), and default + threshold of ~2GB. 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 * Power consumption - storing information in memory is more energy efficient than reading and writing to disk In scenarios where more space in /tmp is needed than available, one can compliment that tmpfs with 'sudo apt-get install swapspace' which will dynamically create/delete swapfile as necessary.
