Fedora 16 grub2-mkconfig

[Nicolae Ghimbovschi]

Hello,

I need help with a GRUB2 issue.

Yesterday I did a preupgrade from F15 to F16.

I've added a new custom menu entry for grub in /etc/grub.d/40_custom

After running grub2-mkconfig -o /boot/grub2/grub.cfg, I saw that
/boot/grub2/grub.cfg was not updated.

grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.1.0-5.fc16.x86_64
Found initrd image: /boot/initramfs-3.1.0-5.fc16.x86_64.img
 No volume groups found
Found Windows 7 (loader) on /dev/sda1
Found Mac OS X on /dev/sda3

Instead  /boot/grub2/grub.cfg.new was created, and it did not contain
my custom menu entry.

What am I doing wrong ? Am I missing a step ?

Below you can see the contents of the following files:
/boot/grub2/grub.cfg,  /boot/grub2/grub.cfg.new and
/etc/grub.d/40_custom

cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry "Mac OS X 10.6.8" {
   set root=(hd0,3)
   chainloader +1
}

/sbin/grub2-mkconfig is just a shell script. grub.cfg.new is the temporary
file it uses for creating and verifying the new config file. Based on your
output quoted above you could find out where the script stops unexpectedly
and without printing an error message. Especially if the problem is
reproducible for you, it shouldn't be difficult to debug the script.

And since this thread has been started on several lists, the "Mac OS X"
entry above means it's this bug:

Thanks! I have applied the patch and it worked :)
changed the following in the
/etc/grub.d/30_os-proberOSXUUID="`grub-probe --target=fs_uuid --device
${DEVICE} 2> /dev/null`"
to
OSXUUID="`grub2-probe --target=fs_uuid --device ${DEVICE} 2> /dev/null`"
