While adding in support for Radius certificates, I decided to refactor a bunch of the code because it seemed a bit convoluted. When all was said and done, I've renamed or added variables and changed both the on boot script 99-udm-le.sh as well as some variables in udm-le.env.
When upgrading be sure to take note and update your udm-le.env file appropriately as well as replacing the script in /mnt/data/on_boot.d or this won't function as it did before.
I'm marking this as a pre-release for a bit until it gets further testing, but the gist of the changes are that you can now force a service restart even if there isn't a new certificate by setting RESTART_SERVICES=true when invoking the script.
Additionally, I've added support for Radius SSL certificates which can be enabled via ENABLE_RADIUS in the environment file.
