This example runs TWO mininet instances, one after the other. This example has both persistent directories mounted on '/var/log'
The first mounts persistent private directories on /var/log and and '/var/run'. It also has a temporary private directory mounted
/var/run. The second mounts temporary private directories on the same on '/var/mn'
directories.
