[Bug 1533639] Re: [ubuntu-cpc] please make /tmp a tmpfs in RAM

[Dustin Kirkland ]

** 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
