I think the same. Vendors don’t care about common location to store defaults,
this can be changed in very unusual ways. My patch for mac80211.sh just add
possibility to override default values for wlan. If specific OpenWrt build
contains /etc/factory_80211, then it will be processed and used, otherwise
radio will be off, ssid = OpenWrt, no encryption, just like as of today.
How to put this configuration into device? This is not a question for OpenWrt
developers, but for people, who build customized OpenWrt firmware. It’s
definitely better to customise build using scripts/configurations in /etc, than
changing /lib/wifi/mac80211.sh, as I saw in some builds.
