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 |

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. |

In Ubuntu, we clear /tmp on every boot.
As such, on servers, by default /tmp should actually be a tmpfs entirely 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
- especially if your disk is spinning media
- and if you're on SSD, this feature extends the life of your flash by reducing your NAND flash writes
* 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
