==== use devfsadm command ====

devfsadm command attempts to load every driver in the system & attach all possible device instances

For new devices devfsadm will:
* create physical device files in /devices directory
* create symbolic links in /dev directory
* manage entries in /etc/path_to_inst file

use devfsadm -c option to limit devfsadm to a particular device class

format: <code>devfsadm -c device_class [-c device_class1 -c device_class2 etc]</code>

values for device_class include disk, tape, port, audio, & pseudo

use devfsadm -i option to limit devfsadm to the name of a specific driver

format: <code>devfsadm -i driver_name</code>

example: devfsadm -i sd limits devfsadm to those disks supported by the sd driver

Include -v option to devfsadm to display verbose output of changes to device tree

Run cleanup routines to remove unreferenced symbolic links & device files for devices no longer attached to system by using devfsadm -C [capital C]
