public string mountable_device (string mountable) throws Error
extract the device part of a mountable
Returns the device name of a mountable. In quite a lot of cases, the mountable is the device name.
However this doesn't apply for btrfs subvolumes, where the mountable is a combination of both the device name and the subvolume path (see also mountable_subvolume to extract the subvolume path of the mountable if any).
