mkdevalloc

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
