That must be my problem, I guess none of my addons “do a backup”.
I believe it would be useful if there was a way to at least backup the list of addons that are installed so I don’t have to guess when my firewall dies and I have to build a new one.
I have a 3D printer that is connected to an RPi running OctoPi / OctoPrint. Their backup records the list of plugins that have been installed and then reinstalls them when you do a restore. This would be the model I’d like to see implemented in IPFire.
