udev print key=”value” pairs for easy import into the udev environment; the keys are prefixed by ID_FS_ or ID_PART_ prefixes.The udev output returns the ID_FS_AMBIVALENT tag if more superblocks are detected, and ID_PART_ENTRY_* tags are always returned for all partitions including empty partitions. This output format is DEPRECATED.
