fstyp_udfcheck for a UDF volume

fstyp_udf device

The fstyp_udf utility is not intended to be run directly, but rather called by fstyp(8) while it is trying to determine which file system type is present on the given device. It returns 1 if it thinks the device contains a UDF volume, and 0 otherwise.
