Description igor.redhat@gmail.com 2011-10-03 21:54:27 UTC 
Description of problem:

After upgrading to kernel 3.1.0-0.rc8, grub2 menu shows (and loads) the correct version in the main prompt but "Loading" prompt still says "rc6". Also, older kernel versions that are no longer installed are still shown in grub menu.

How reproducible:

I started out with Fedora 16 Alpha DVD installed and never mucked around with grub config manually.


Expected results:

Correct kernel version is shown in "Loading" line and removed kernel versions removed from the grub menu.

Same issue after upgrading to 3.1.0-0.rc8.git0.1:

Comment 3 Mattia Verga 2011-10-09 08:38:19 UTC 
I can confirm this.
Comment 4 Dr. Tilmann Bubeck 2011-10-11 20:40:59 UTC 
This seems to be a bug in grubby, because grubby is used in kernel-updates through %post with /sbin/new-kernel-pkg

Patch based upon grubby-8.3 to fix the problem.
Comment 6 Dr. Tilmann Bubeck 2011-10-12 19:58:07 UTC 
This is a bug in grubby-8.3. Please find attached a patch which fixed this problem.

What went wrong?

grubby searches the template file for lines containing "Loading Linux" and will append the version number after that text. However, Fedora does not contain "Loading Linux", but "Loading Fedora". So this line is never detected as such a "special" line and therefore the current linux version number is never appended.

Instead the line is copied unchanged. Therefore you will stick with the message generated at install time from anaconda. It will never change.

How was it fixed?
We now detect "Loading Linux" AND "Loading Fedora" as such "special" lines. Therefore the version number is appended.

Feel free to apply upstream.

/me polishes his ego: Bug 732654 already had a patch for this when this duplicate issue was filed.
Comment 10 Andre Robatino 2011-10-17 16:32:51 UTC 
Closed as a duplicate since essentially the same exact patch was already available in https://bugzilla.redhat.com/show_bug.cgi?id=732654#c9 .
