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.

    set root=(hd0,3)

You may get more help on the test list.
They have benn using grub2 for a while longer:

Not sure if you're seeing the same issue I had, but I had a similar 
problem with grub2 a week or two back. The cfg file was not getting 
updated. I tracked it down to a bug in this file

/etc/grub.d/30_os-prober

It made reference to grub-probe when it should have been grub2-probe. 
This was causing grub2-mkconfig to fail to update the file (without an 
error message too). Replacing grub-probe with grub2-probe in that file 
might help.

Alternatively adding the following to /etc/grub/default will disable the 
os prober (if you don't need it anyway, ie if you're not dual/tripple 
booting etc)

GRUB_DISABLE_OS_PROBER=true

Which is related to the macosx boot entry creation only, however:
https://bugzilla.redhat.com/737203

[Nicolae Ghimbovschi]

Thanks! I have applied the patch and it worked :)

changed the following in the /etc/grub.d/30_os-prober
OSXUUID="`grub-probe --target=fs_uuid --device ${DEVICE} 2> /dev/null`"

to

OSXUUID="`grub2-probe --target=fs_uuid --device ${DEVICE} 2> /dev/null`"

I applied that patch and modified my /etc/default/grub file in order to change the colors of the text, as seen in [1]:

$ cat /etc/default/grub
GRUB_CMDLINE_LINUX="quiet rhgb"
GRUB_COLOR_NORMAL="light-blue/black"
GRUB_COLOR_HIGHLIGHT="light-cyan/blue"

and then updated:

$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg

...but no luck! Any help?
