Hello,
I have a warning generated by grub2-mkconfig that shows up on various
systems that I'm not sure what to do about. Well, I know I can ignore
it, but I'm not sure what do do about not getting the warning in the
first place.
On this machine here, I have
menuentry 'Fedora, with Linux 3.14.9-200.fc20.x86_64' --class ...
and grub2-set-default 'Fedora, with ...' is OK, but then
and I also have GRUB_DISABLE_SUBMENU=true i /etc/default/grub, so
$ grub2-mkconfig -o /boot/grub2/grub.cfg
...
Warning: Please don't use old title `Fedora, with Linux
3.14.9-200.fc20.x86_64' for GRUB_DEFAULT, use `Advanced options for
Fedora>Fedora, with Linux 3.14.9-200.fc20.x86_64' (for versions before
2.00) or
`gnulinux-advanced-d87b5f54-5bfb-45bd-b300-f4b1db6d5dfb>gnulinux-3.14.9-200.fc20.x86_64-advanced-d87b5f54-5bfb-45bd-b300-f4b1db6d5dfb'
(for 2.00 or later)
Exhorting me to use a submenu default when there are no submenus is
clearly wrong, so in /etc/grub.d/10_linux (and the other
platform-specific files) there's:
> if [ x"$title" = x"$GRUB_ACTUAL_DEFAULT" ] || [ x"Previous Linux
> versions>$title" = x"$GRUB_ACTUAL_DEFAULT" ]; then
> replacement_title="$(echo "Advanced options for ${OS}" | sed
> 's,>,>>,g')>$(echo "$title" | sed 's,>,>>,g')"
> quoted="$(echo "$GRUB_ACTUAL_DEFAULT" | grub_quote)"
> title_correction_code="${title_correction_code}if [ \"x\$default\"
> = '$quoted' ]; then default='$(echo "$replacement_title" | grub_quote)'; fi;"
> grub_warn "$(gettext_printf "Please don't use old title \`%s' for
> GRUB_DEFAULT, use \`%s' (for versions before 2.00) or \`%s' (for 2.00 or
> later)" "$GRUB_ACTUAL_DEFAULT" "$replacement_title"
> "gnulinux-advanced-$boot_device_id>gnulinux-$version-$type-$boot_device_id")"
> fi
It's easy enough to add a test for GRUB_DISABLE_SUBMENU here but I'm at
a loss to know why this clause is needed at all. I know it means that
if I have submenus enabled then I can just set the default to be the
title of a submenu and not worry about the "Advanced options ..." bit,
but it looks to me as though it was just a transition thing which is
really no longer needed.
Is this really no longer needed or am I missing something? I'm happy to
submit a patch either way.
