+# ${ROOTFS} - indicates a filesystem image to include as the root filesystem (optional)
+# ${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
