* @(#)disktab.h 5.2 (Berkeley) 10/1/85
* 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.
