disktab -- disk description file
SYNOPSIS
#include <disktab.h>
DESCRIPTION
disktab is a simple database which describes disk geometries and disk partition characteristics. It is used to initialize the disk label on
the disk. 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.
