Hi All,

Besides using a hook I can use copy the essid/interfaces file being
used to another temporary location, substituting the default network
interface reference in the file with the network device being used to
connect or disconnect. However, this writes to disk every time ifup
and ifdown is used. Preferably, a memory resident file system is used.
If I can use a memory file system, I will be able to go ahead with
little changes.
