Any idea how to make darkice work on raspberry pi readonly filesystem ?

[acca84]

Hello
I'd like to use darkice + icecast2 on a raspberry pi running Buster
I'd like to make the image readonly in order to avoid image corruptions, like in this example :

Any idea of modifications to make to darkice (and icecast) to work please ?
Thanks
