I'm wondering if the factory openwrt version has a configuration log?
Another musing is if a crowd-funded project could be set with OpenWrt to buy 500 - 1000 units with OpenWrt logos and flashed with initramfs. The buyer could then download a release or make a custom image. The price of the units would include a donation to the OpenWrt project. It also looks like larger flash chips can be specified
To me, this would be better then most devices on the market. Frequent security updates, more flexibility, open code for review by anyone concerned about backdoors and community support.
