Details:
Under Gentoo Linux with sys-boot/grub-2.02_beta2-r9 I get this error:
With
GRUB_TERMINAL_INPUT="usb_keyboard0 serial_usb0 console"
GRUB_TERMINAL_OUTPUT="serial_usb0 console"
GRUB_SERIAL_COMMAND="sleep --verbose --interruptible 1; serial --speed=115200
usb0"
GRUB_PRELOAD_MODULES="nativedisk ehci ohci uhci usb usbserial_ftdi"
in /etc/default/grub you get:
# grub2-mkconfig -o /boot/grub/grub.cfg
Invalid output terminal "serial_usb0 console"
This can be fixed by changing /usr/sbin/grub2-mkconfig from
for x in ${GRUB_TERMINAL_OUTPUT}; do
case "x${x}" in
xgfxterm) ;;
xconsole | xserial | xofconsole | xvga_text)
# make sure all our children behave in conformance with ascii..
export LANG=C;;
*) echo "Invalid output terminal \"${GRUB_TERMINAL_OUTPUT}\"" >&2 ;
exit 1 ;;
esac
done
to (note the appended * after xserial)
for x in ${GRUB_TERMINAL_OUTPUT}; do
case "x${x}" in
xgfxterm) ;;
xconsole | xserial* | xofconsole | xvga_text)
# make sure all our children behave in conformance with ascii..
export LANG=C;;
*) echo "Invalid output terminal \"${GRUB_TERMINAL_OUTPUT}\"" >&2 ;
exit 1 ;;
esac
done
But now the GRUB_SERIAL_COMMAND isn't added to grub.cfg because of the
following lines
in /etc/grub.d/00_header
for x in ${GRUB_TERMINAL_INPUT} ${GRUB_TERMINAL_OUTPUT}; do
if [ xserial = "x$x" ]; then
serial=1;
fi
if [ xgfxterm = "x$x" ]; then
gfxterm=1;
fi
done
After changing these lines to
for x in ${GRUB_TERMINAL_INPUT} ${GRUB_TERMINAL_OUTPUT}; do
case "x${x}" in
xgfxterm) gfxterm=1;;
xserial*) serial=1;;
esac
done
now
# grub2-mkconfig -o /boot/grub/grub.cfg
creates a valid and working config.
