    NAME

    
    
    devfs.conf
    
     - boot-time devfs configuration information
    
     
    

    DESCRIPTION

    The file provides an easy way to set ownership and permissions, 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.rules5 for setting ownership and permissions for all device nodes, and devd.conf5 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 rules consist of three parameters separated 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 parameter 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 parameter must be a mode as explained in chmod(1).

     

    FILES

    EXAMPLES

    To create a /dev/cdrom link that points to the first SCSI(4) or atapicam(4) CD-ROM, the following may be added to :
    link    cd0     cdrom
    

    Similarly, to link /dev/cdrom to the first ATAPI CD-ROM device, the following action may be used:

    link    acd0    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
