ITS WiFi Access Points Setup
============================
We build the access points in use at the space using the OpenWrt image
builder. The deployed images are completely hands-off. No configuration of the
running firmware should be necessary as all the device specific setup is done
using `/etc/uci-defaults/` by keying off the device's MAC address.
This directory contains the scripts and configuration for the automated building
of OpenWrt image-build based firmware images.
We use this to build fully pre-configured images for our 802.11
access-points. The deployed images are completely hands-off. No configuration of
the running firmware should be necessary as all the device specific setup is
done using `/etc/uci-defaults/` by keying off the device's MAC address.
See [`files/common/its/etc/uci-defaults/50-config-from-mac`](files/common/its/etc/uci-defaults/50-config-from-mac) for details.
Note that some of the files in this repository contain secrets, like
passwords. These files are stored using
[git-annex](https://git-annex.branchable.com/) which merely stores a hash in the
(public) git repo and ships the relevant file contents off to a fileserver or
other internal storage location.
