device-map(4)                                                 device-map(4)


   NAME
         device-map - script for makedev

   DESCRIPTION
         The /etc/device-map file controls the assignment of generic device
         names for system administration and generic use.

         The /etc/device-map file contains two kinds of lines:  comment lines
         and assignment lines.

         1.  Any line starting with the # character is assumed to be a
             comment.

         2.  An assignment line consists of two fields separated by white
             space (tab or space characters).  The first field specifies the
             generic device type (for example, ctape, disk, ninetrack).  The
             second field contains the controller-specific name of the device
             that will be assigned that generic name (for example,
             /dev/rmt/m350-c0d0).

         The generic device number is assigned automatically, based on the
         position of the assignment line relative to other generic assignment
         of that type.

         If the controller-specific device does not exist or is of the
         incorrect type, the assignment line is ignored.  Processing continues
         on other legal assignment lines.

         A partial example of an /etc/device-map file is presented below:

                     .
                     .
               #   Cartridge tapes devices
               ctape /dev/rmt/m350_c0d0
               ctape /dev/rmt/m328_c0d4
                     .
                     .
