DESCRIPTION
Disktab is a simple datebase which describes disk geometries and
disk partition characteristics. The format is patterned after
the termcap(5) terminal data base. Entries in disktab consist of
a number of `:' separated fields. The first entry for each disk
gives the names which are known for the disk, separated by `|'
characters. The last name given should be a long name fully
identifying the disk.
The following list indicates the normal values stored for each
disk entry.
