NVRAM. The custom configuration file must use cfg as the filename extension.
When the system attempts to load a custom configuration file, configuration files on NVRAM have
priority over configuration files on the router's compact flash.
The priority for loading a configuration file is as follows:

have priority over configuration files on the router's flash drive and the "customer-config.SN" file name
has priority over the customer-config file name.
The priority for loading a configuration file is as follows:
1. usbflash0:customer-config.SN
