Grubby Ignores grub.cfg Submenu Entries on Kernel Update
Last modified: 2013-02-13 16:10:45 EST
Description of problem:
When I update the kernel on my F16 machine w/ Xen Dom0, grubby ignores all of the Xen related submenu entries.
The consequence of this is that none of the Xen menus get updated to contain the new kernel and my default is changed from "Xen 4.1.1" to "0" since that was the only entry that was updated
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Xen Dom0
2. set GRUB_DEFAULT="Xen 4.1.1" in /etc/defaults/grub
3. update kernel
Only entries that are not inside a menu are updated with the new kernel version and the default boot option is no longer using Xen
All menus are updated with new submenu entries for the newly installed kernel and the default is not changed

Grub.cfg after kernel update
Created attachment 529955 [details]
freshly generated grub.cfg before kernel update
This was first seen on Bug 744717

With the patch on Bug 744717 grub.cfg will remain well-formed.
I doubt it is feasible to teach grubby how to patch submenus "correctly".
This message is a reminder that Fedora 16 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 16. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '16'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 16's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 16 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" and open it against that version of Fedora.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
