/*
 * HISTORY:
 * 16-Mar-88  John Seamons (jks) at NeXT
 *	Cleaned up to support standard disk label definitions.
 *
 * 24-Feb-88  Mike DeMoney (mike) at NeXT
 *	Added d_boot0_blkno to indicate logical block number
 *	of "block 0" boot.  This blkno is in d_secsize sectors.
 *	Added d_bootfile to indicate the default operating system
 *	image to be booted by the blk 0 boot.
 *	Changed d_name and d_type to be char arrays rather than ptrs
 *	so they are part of label.  This limits length of info in
 *	/etc/disktab, sorry.
