The past weeks I’ve been exploring the OpenWrt build system (https://openwrt.org/) and I’m planning to use this for building the next ChirpStack Gateway OS images, thus migrating from Yocto. One of the biggest advantages over Yocto (https://www.yoctoproject.org/) is that it provides a really nice web-interface and configuration framework, which provides many configuration options out-of-the-box. As well it is fairly easy to add new configuration screens to the web-interface, to handle the ChirpStack configuration options.
This will also make it possible to search for and install additional software with just a few clicks. This feature has been requested quite a few times and the current answers was to setup a local Yocto build environment and re-build the images which is not ideal (as compiling the build environment already takes a few hours on most machines).
Unfortunately the upgrade process would mean to re-flash the SD Card, but I think this migration will make the ChirpStack Gateway OS a lot more user-friendly 
A few previews of how this is probably going to look like:
I expect to be able to share the first test-images soon (within weeks).
