- * Note: the VTOC is not implemented fully, nor in the manner
- * that AT&T implements it. AT&T puts the vtoc structure
- * into a sector, usually the second sector (pdsector is first).
- *
- * Sun incorporates the tag, flag, version, and volume vtoc fields into
- * its Disk Label, which already has some vtoc-equivalent fields.
- * Upon reading the vtoc with read_vtoc(), the following exceptions
- * occur:
- * v_bootinfo [all] returned as zero
- * v_sanity returned as VTOC_SANE
- * if Disk Label was sane
- * v_sectorsz returned as 512
- * v_reserved [all] returned as zero
- * timestamp [all] returned as zero
- *
- * See dklabel.h, read_vtoc(), and write_vtoc().
