In dropbear.config we have:

config dropbear
    option PasswordAuth 'on'
    option Port         '22'

Yet in dropbear.init there's no mention of the on option.

config_cb() {
    local cfg="$CONFIG_SECTION"
    local nopasswd
    local cfgt
    config_get cfgt "$cfg" TYPE

    case "$cfgt" in
        dropbear)
            config_get passauth $cfg PasswordAuth
            config_get port $cfg Port

            case "$passauth" in
                no|off|disabled|0) nopasswd=1;;
            esac
            DROPBEAR_ARGS="${nopasswd:+-s }${port:+-p $port}"
        ;;
    esac
}

So what's the proper method for someone who wants to use a public/private key pair?
Is it off or nopasswd?  I'm guessing it's nopasswd after looking at the code but don't really want to lock myself out so thought I'd ask.

isn't it just

option PasswordAuth 'off' or
option PasswordAuth 'no' or
option PasswordAuth 'disabled' or
option PasswordAuth '0'

Yeah, that worked...just required a powercycle as "/etc/init.d/dropbear stop && /etc/init.d/dropbear start" locked me out.
I have serial console access anyway, so I don't know what I was worried about.
