I was going by the example of one of the other platforms, I forget which. Maybe target/linux/atheros/base-files/etc/uci-defaults/network ... I can change the Wifi to be off, and change the SSID. The reason I put values was as placekeepers, so that someone getting into /etc/config/wifi would be able to see what they needed to change by hand. I'm not sure there are any Alix's currently in production with 2 miniPCI slots, or if there ever have been. I also decided to do it as a series of mods applied to the standard configuration, so that if the "main" canned config changed, I wouldn't have to modify the platform configs as well. They would just layer their changes atop the main configuration as deltas. -Philip
