Something like
#!/bin/sh
set -e
if test -e /boot/memtest86+.bin ; then
if test -r /usr/lib/grub/grub-mkconfig_lib ; then
. /usr/lib/grub/grub-mkconfig_lib
MEMTESTPATH=$( make_system_path_relative_to_its_root "/boot/memtest86+.bin"
)
echo "Found memtest86+ image: $MEMTESTPATH" >&2
cat << EOF
menuentry "Memory test (memtest86+)" {
EOF
prepare_grub_to_access_device ${GRUB_DEVICE_BOOT} | sed -e "s/^/\t/"
cat << EOF
linux16 $MEMTESTPATH
}
menuentry "Memory test (memtest86+, serial console 115200)" {
EOF
prepare_grub_to_access_device ${GRUB_DEVICE_BOOT} | sed -e "s/^/\t/"
cat << EOF
linux16 $MEMTESTPATH console=ttyS0,115200n8
}
EOF
else
. /usr/lib/grub/update-grub_lib
MEMTESTPATH=$( make_system_path_relative_to_its_root "/boot/memtest86+.bin"
)
echo "Found memtest86+ image: $MEMTESTPATH" >&2
cat << EOF
menuentry "Memory test (memtest86+)" {
linux $MEMTESTPATH
}
menuentry "Memory test (memtest86+, serial console 115200)" {
linux $MEMTESTPATH console=ttyS0,115200n8
}
EOF
fi
fi
?
(Totally untested.) At least, the second part works in memtest86+
2.11-3 with grub-pc 1.96+20080724-16.
