Hello,
I'm doing my first firmware upgrade and followed https://openwrt.org/docs/guide-user/installation/generic.sysupgrade
I installed Opkg extras and Hotplug extras. I did 'opkg save', then downloaded the complete configuration tarball via LuCI, then flashed the file
https://downloads.openwrt.org/releases/21.02.2/targets/ipq806x/generic/openwrt-21.02.2-ipq806x-generic-netgear_r7800-squashfs-sysupgrade.bin
After rebooting the new firmware, all settings are still there, everything is working. But afaik I would need to restore all my custom packages via 'opkg restore' now? But all packages like travelmate, vpnc, etc. are still there, eventhough I confirmed the new firmware version is up and running. Why? So restoring custom packages as described in the documentation is not required anymore?
