want to display what's currently playing on my magic mirror. Preferably via shairport's function to send metadata to a UDP listener. Alternatively to a MQTT broker (probably better functionality but would mean for me to install such a broker in the first place).
Question 1: the shairport running on the standard hifiberry distribution, does it support MQTT and UDP metadata-forwarding?
Question 2: when I touch shairport's config file, what happens at the next software update? Will it be overwritten?
