DISKTAB(5) BSD File Formats Manual DISKTAB(5)NAME
disktab -- disk description file
SYNOPSIS
#include <disklabel.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 field for each entry gives the names by which a disk's entry may be selected, separated by `|' characters. The last name given
should be a long name fully identifying the disk.
The optional fields for each entry are:
