Watch for dynamips rom & nvram change
This monitor for change the file from dynamips by computing a
hash of the watched file.

The way dynamips work prevent the update of the modification time.

We can improve that by using native system for watching file but:
* it's require dependencies specific for each OS
* dependencies use C extensions
* this is only a backup if your router is cleanly shutdown we export
stuff
