Description mrdvt92 2011-05-05 00:30:54 UTC 
Description of problem: 

When upgrading from kernel-2.6.38.4-20.fc15.x86_64 to kernel-2.6.38.5-22.fc15.x86_64 the /etc/grub.conf file changed my default=0 from 

title Windows 7
	rootnoverify (hd0,0)
	chainloader +1

to the new kernel

Version-Release number of selected component (if applicable):

kernel-2.6.38.5-22.fc15.x86_64

$ rpm -q --whatprovides /etc/grub.conf
file /etc/grub.conf is not owned by any package

$ cat /etc/redhat-release 
Fedora release 15 (Lovelock)

How reproducible:

It happen for both kernel-2.6.38.4-20.fc15.x86_64 and kernel-2.6.38.5-22.fc15.x86_64

Steps to Reproduce:
1. Install FC15
2. Edit /etc/grub.conf to put three windows lines in the zero location
3. run yum update (when there's a new kernel)
4. Reboot and Fedora 15 is the default not Win 7
  
Actual results:
Reboot and Fedora 15 is the default not Win 7

Expected results:
For a yum update to not change my default

Comment 1 Chuck Ebbert 2011-05-05 07:05:58 UTC 
Edit /etc/sysconfig/kernel and set UPDATEDEFAULT=0
Comment 2 mrdvt92 2011-05-06 03:22:53 UTC 
Chuck,
I guess I want a less black and white solution.  

What I would like is for Fedora, out of the box, to update to the default kernel if it is already the default but not update the default if another distribution or OS is the default.

I've implemented the sysconfig work around but would like to see a long term enterprise solution.

$ cat /etc/sysconfig/kernel 
# UPDATEDEFAULT specifies if new-kernel-pkg should make
# new kernels the default
UPDATEDEFAULT=no

I didn't find any documentation of the sysconfig file syntax.  However, it appears the value should be set to "no" instead of "0".  But, maybe both will work.

We'll see how it works when the next kernel comes out.

Thanks,
Mike
