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

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
