-/** @page how_mount_works How mount works in barebox
- *
- * Mounting a filesystem ontop of a device is working like devices and drivers
- * are finding together.
- *
- * The mount command creates a new device with the filesystem name as the
- * driver for this "device". So the framework is able to merge both parts
- * together.
- *
- * By the way: With this feature its impossible to accidentely remove
- * partitions in use. A partition is internally also a device. If its mounted
- * it will be marked as busy, so an delpart command fails, until the filesystem
- * has been unmounted.
