Comment (by kallisti5):

 Ok... here are some ideas for a more long-term fix:

  * If swap is undefined (we can call this "automatic" the future)
    * Swap size defaults to (ram * 2)
    * If (ram * 2) is > 25% of the freespace, use the 25% of the free space
 as swap
      * If 100MB free, top swap is 25MB
      * If 1GB free, top swap is 250MB
      * If 10GB free, top swap is 2.5GB (this is however limited by the
 (ram * 2))
  * If swap is defined:
    * If swap larger then free space
      * Log this event
      * Set swap to 98% of free space for this boot only.
        * We could have a low disk space notification that would give an
 overall alert that freespace is low.
