Details - I want to merge settings to an already existing uci config file with a script in /etc/uci-defaults 

uci provides an -m option for merging settings. This works fine with options but 'list' settings are duplicated. 

I'd thought that merging should not duplicate the list entries - and have the same behavior with the option entries. 

How to reproduce: 

create a script i.e. 10-test-uci-import.sh 


#!/bin/sh

. /lib/functions.sh 

uci -m import test
