That's not what the <disk> element is for. <disk> is about exposing
block device nodes to the container. It shouldn't try todo anything
with this device nodes. They might be used as raw data storage by
an application, so we can't assume they should be mounted.
If you want to mount things then you should be using <filesystem>
