Description Tom Horsley 2011-10-09 13:25:55 UTC

Description of problem:

I had previously modified my /etc/default/grub file to have different
default kernel options (remove rhgb, etc) and also to disable the os prober.

Today I got new updates and my /etc/default/grub file is back to the
original contents as shipped with grub2.

I thought this was supposed to be the file where customizations were
intended to be made.


Version-Release number of selected component (if applicable):
grub2-1.99-7.fc16.x86_64

How reproducible:
Just got the update, so can't really try again.

Steps to Reproduce:
1.get grub2 update
2.see /etc/default/grub replaced
3.
  
Actual results:
customizations wiped out

Expected results:
customizations retained

Comment 1 Tom Horsley 2011-10-13 23:38:49 UTC

Another grub2 update, and another /etc/default/grub has been set
back to what is apparently the grub2 default contents, the one line:

GRUB_CMDLINE_LINUX="quiet rhgb"

When I first installed f16 beta from the dvd, there was a whole bunch
of customizations added to /etc/default/grub, customizations which
are apparently responsible for the different kinds of menu entries
I see in the initial grub.cfg file.

By constantly wiping out /etc/default/grub, you also wipe out the
ability to regenerate a grub.cfg file that looks even vaguely like
the one you get following the initial anaconda install.

What is the point of /etc/default/grub? Why not just hard code the
default if every grub2 update is going to wipe out custom settings?

I just installed grub2-1.99-9.fc16.x86_64 and got this behavior.

Comment 2 Tom Horsley 2011-10-14 00:26:48 UTC

This is the sort of content anaconda leaves in /etc/default/grub:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Fedora"
GRUB_DEFAULT=saved
GRUB_CMDLINE_LINUX="rd.md=0 rd.lvm=0 rd.dm=0  KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0 LANG=en_US.UTF-8"

I usually want to add:

GRUB_DISABLE_OS_PROBER="true"

since I chainload f16 and don't want f16's menu cluttered up with
things I already get to a different way.

Anyway, this all goes away when I get a new grub2 update.
