Great news - what you're wishing for mostly already exists[1]. The relatively new sysupgrade server and attended-sysupgrade clients automate the process of creating custom images matching already installed packages. After the breaking network config change a few years ago, it's now pretty safe to keep config files and ssh keys while flashing an upgrade image. The end result now is that I can seamlessly and painlessly update my OpenWRT boxes with just a few clicks or commands, despite loads of installed packages and config files.

Thanks, I just used luci-app-attendedsysupgrade to upgrade from 23.05.0-rc2 to -rc3 with minimal pain. The only problem is that it lost my scripts in /root.
