Replace soundpack on roborock s6 pure

[francois-pasquier]

Hi, thank you for the hard work!

As the filesystem for /opt is read-only on s6 pure, I am looking for a solution to replace the installed soundpack. I tried with Valetudo and it fails with an error 3

I also hope it's the right place to discuss this as the error is coming from miio_client when calling dnld_install_sound

in the startup scripts (check your dustbuilder fw home dir for root) you can bind-mount a directory from a writable partition into /opt.
