The main question here is whether I can locate some alternately-named configuration files in /etc/config and expect them to get ignored? Say, wireless.old or dhcp.old, for example.
In case it's relevant, I've reconfigured a router with some new temporary settings since I'm checking that it's properly functioning, all while it is connected to my LAN behind the router it's due to replace. When I'm sure it's good to go I'll go in and change all its temporary settings to the proper values, reboot the network and put it in place of the current router.
Input on this question will be appreciated.
