| 15 | _\bD_\bi_\bs_\bk_\bt_\ba_\bb is a simple database which describes disk geometries | |
| 16 | and disk partition characteristics. It is used to initial- | |
| 17 | ize the disk label on the disk. The format is patterned | |
| 18 | after the _\bt_\be_\br_\bm_\bc_\ba_\bp(5) terminal data base. Entries in _\bd_\bi_\bs_\bk_\bt_\ba_\bb | |
| 19 | consist of a number of `:' separated fields. The first | |
| 20 | entry for each disk gives the names which are known for the | |
| 21 | disk, separated by `|' characters. The last name given | |
| 22 | should be a long name fully identifying the disk. | |
| 23 | ||
| 24 | The following list indicates the normal values stored for | |
| 25 | each disk entry. | |
