write mem if running-config and startup-config are different?

[Matt Wilson]

Hi-

We would like to catch and remedy situations where we have altered a 
switch's running-config, but then forget to write mem (weeks later, 
the switch reboots due to power outage, and suddenly vlans aren't 
working, etc).

Is anyone using rancid to notice that running-config and 
startup-config are different, and if so, issue a write mem command? 
(or something else to address such an issue?)  Would you be willing 
to share what you've done?

Thanks-
Matt
