DEVFS.CONF(5)		      File Formats Manual		 DEVFS.CONF(5)

NAME
       devfs.conf -- boot-time devfs configuration information

DESCRIPTION
       The  devfs.conf	file provides an easy way to set ownership and permis-
       sions, or create	links for devices available at boot.

       It does not work	for devices plugged in and out after the system	is  up
       and  running,  e.g. USB devices.	 See devfs.rules(5) for	setting	owner-
       ship and	permissions for	all device nodes, and devd.conf(5) for actions
       to be taken when	devices	are attached or	detached.

       Lines starting with a hash sign (`#') and empty lines are ignored.  The
       lines that specify devfs.conf rules consist of three  parameters	 sepa-
       rated by	whitespace:

       action  The  action  to take for	the device.  The action	names are only
	       significant to the first	unique character.

       devname
	       The name	of the device created by devfs(5).

       arg     The argument of the action.

       The actions currently supported are:

       link    This action creates a symbolic link named arg  that  points  to
	       devname,	the name of the	device created by devfs(5).

       own     This  action changes the	ownership of devname.  The arg parame-
	       ter must	be in the form of an owner:group  pair,	 in  the  same
	       format used by chown(8).

       perm    This  action changes the	permissions of devname.	 The arg para-
	       meter must be a mode as explained in chmod(1).

FILES
       /etc/devfs.conf
       /usr/share/examples/etc/devfs.conf

EXAMPLES
       To create a /dev/cdrom link that	points to the first CD-ROM,  the  fol-
       lowing may be added to devfs.conf:

	     link    cd0     cdrom

       To set the owner	of a device, the own action may	be specified:

	     own     cd0     root:cdrom

       To set the permissions of a device, a perm action should	be used:

	     perm    cd0     0660
