mkdevalloc(1M)                                            System Administration Commands                                            mkdevalloc(1M)

NAME
       mkdevalloc - Make device_allocate entries

SYNOPSIS
       /usr/sbin/mkdevalloc

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

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

       Entries are generated based on the device special files found in /dev. For the different categories  of  devices,  the  mkdevalloc  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/sr*, /dev/nsr*, /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
       frame buffer    /dev/fb

       All  entries  set  the  device-minimum  and device-maximum fields to the hex representations of ADMIN_LOW and ADMIN_HIGH, respectively. The
       device-authorization field is set to solaris.device.allocate, except for the framebuffer entry, where it is  set  to  *.  The  device-name,
       device-type and device-clean fields are set to the following values:

                       device-name      device-type   device-clean

       audio           audio            audio         audio_clean_wrapper
       tape            mag_tape_0,1,... st            st_clean
       floppy          floppy_0,1,...   fd            disk_clean
       removable disk  cdrom_0,1,...    sr            disk_clean
       frame buffer    framebuffer      fb            /bin/true
