# External variables
|
# ${INITRD} - indicates a list of filesystem images to concatenate and use as an initrd (optional)
|
# ${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
