Debian LiveBuild: How to make the bootloader to directly boot to live?

Question

I just start learning on using LiveBuild. I want it to boot directly in 'Live' mode, no other boot choice(s)

Here is my auto/config

#!/bin/sh

set -e

lb config noauto \
    --mode debian \
    --distribution buster \
    --architectures i386 \
    --linux-flavours 686-pae \
    --debian-installer false \
        --apt-recommends false \
        --debootstrap-options "--variant=minbase" \
        --firmware-chroot false \
    --apt-indices false \
        --bootloaders syslinux \
    --memtest none \
"${@}"

here is my config/bootloaders/syslinux/syslinux.cfg

include menu.cfg
#default vesamenu.c32
default live-@FLAVOUR@
prompt 0
timeout 1

And here is config/bootloaders/syslinux/menu.cfg

menu hshift 0
menu width 82

menu title Boot menu
#include stdmenu.cfg
timeout 1
label live-@FLAVOUR@
    menu label ^Live (@FLAVOUR@)
    menu default
    linux @LINUX@
    initrd @INITRD@
    append @APPEND_LIVE@

But still when booted, it always show the standard boot menu and do nothing until I press ENTER.

Kindly please give me some clue to fix this problem

Answer 1

If you still haven't found your answer, I'm guessing that the bootloader on your live media isn't actually syslinux.

You can check it by simply opening your live media and looking at the folders in it: often it isn't syslinux but isolinux. In this case you need to have a template for it in the folder config/bootloaders (you can get one in /usr/share/live/build/bootloaders).

For the timeout setting, the *.cfg in isolinux is similar to the syslinux one.

Answer 2

You are booting in isolinux because you boot in BIOS mode.
