 +  - Make a backup copy of /etc/fstab
 +  - create a 4G file to be used for swap space. modify size as necessary
 +  - Create the entry in fstab for the swap space
 +  - turn on swap
 +  - create a tmpfs entry in fstab for /tmp
 +  - move /var/tmp to point to /tmp
 +  - activate /tmp. This could cause instability if something is being used, so reboot very soon
 +  - display mounts (prove we did what we expected to)
 +  - reboot to be on safe side
