NAME

       mkdevmaps - make device_maps entries

SYNOPSIS

       /usr/sbin/mkdevmaps

DESCRIPTION

       The  mkdevmaps  command	writes	to standard out a set of device_maps(4) entries describing the system's frame buffer, audio, and removable

       The mkdevmaps command is used by the init.d(4) scripts to create or update the /etc/security/device_maps file.

       Entries are generated based on the device special files found in /dev. For the different  categories  of  devices,  the	mkdevmaps  command
       checks for the following files under /dev:

       audio	       /dev/audio, /dev/audioctl, /dev/sound/...
       tape	       /dev/rst*, /dev/nrst*, /dev/rmt/...
       floppy	       /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
       removable disk  /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
       frame buffer    /dev/fb
