We have finished the dev of a system of \"save\" of switch configuration
with a failover configuration in case of problem.

The problem is due to the fact that the NVRAM of several switches
is not sufficient to save all the switch configuration
If we try to do a \"wr m\" alias \"copy run start\"
the switch crashes.

We have implemented a system that dump configurations
and verify the size and then decide whether to do a \"wr m\" or
purging the configuration of certain lines and saves
a minimal configuration. Then another that detects that
the switch has restarted then puts in the switch remaining configuration.
