If you want to save and reinstall user installed package(s) after firmware upgrade, this is the script that I use
Script name: overlaypkgs.sh

Usage : overlaypkgs.sh backup
This command simply creates a list from /overlay drive for user installed package(s) in /etc/config. If you keep your settings during the firmware upgrade process you will have this file after the upgrade or you can save /etc/config/overlaypkgs.lst file somewhere else.
overlaypkgs.sh restore
Make sure that your created user package(s) list file is ready. Enter this command after the firmware upgrade and enjoy your new system without missing anyhting.
Has this feature been implemented by now? I remember when I upgraded my FB4040 to OpenWRT 21.x it was not implemented, I had to install all my additional packages manually again. I'd like to upgrade to version 23 now, so I'd like to know if I need to run this script by hand or if things will go more smoothly this time.
