Default Fedora 16 grub2

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
}
