I've now read parts of the wiki and I am asking if there is any test for configuration files, so if there are syntax errors, the change won't be applied. Does such a feature exist?
My device has no RS232 (only UART inside), so making it inaccessible from the network is a nasty thing.
If I'm not mistaken you can do uci show /etc/config/network which should cover your ass for obvious dump errors as a missing single quote. If I would have done so it would have saved me a couple of times too.... But I forget about it every time....
