# ${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
