- # ${AUTO_SYSLINUXMENU} - set this to 1 to enable creating an automatic menu
- # ${LABELS} - a list of targets for the automatic config
- # ${APPEND} - an override list of append strings for each label
- # ${SYSLINUX_OPTS} - additional options to add to the syslinux file ';' delimited
- # ${SYSLINUX_SPLASH} - A background for the vga boot menu if using the boot menu
- # ${SYSLINUX_DEFAULT_CONSOLE} - set to "console=ttyX" to change kernel boot default console
- # ${SYSLINUX_SERIAL} - Set an alternate serial port or turn off serial with empty string
- # ${SYSLINUX_SERIAL_TTY} - Set alternate console=tty... kernel boot argument
- # ${SYSLINUX_KERNEL_ARGS} - Add additional kernel arguments
