Removing package ddns-scripts from root...

Model TP-Link TL-WR940N v4
Firmware Version LEDE Reboot 17.01.2 r3435-65eec8bd5f / LuCI lede-17.01 branch (git-17.152.82987-7f6fc16)
Kernel Version 4.4.71

Welcome to LEDE !

My guess is that this is incorporated into the firmware image and that it cannot be removed since it does not resides onto the /overlay part.

All devices with low specifications like yours are limited in what you can do with it. Have a look at the 4/32 warning. Basically with that low memory, you will frequently exhaust your RAM and run into problems (device hang/reboot, etc.).

Unless you start building your very own firmware and cut the branches here and there, you will likely not have much space left :cry:
