We are working on an AWS IoT client solution for which we need to integrate rotating keys. Now, I found this article: Rotate keys and certificates for IoT which suggests making use of balena environment variables. The problem is, the device must not reboot when its env variables are updated. Is there a way to use/update balena environment variables without the need to reboot the device? The problem is, we have spotty internet coverage which ultimately will mean, that device reboots happen at random times & locations which we cannot allow for.
Thanks for and ideas, inputs & suggestions
