Description Michal Schmidt 2012-04-26 06:26:00 EDT
Description of problem:
It appears that the GRUB menu gets confused by tab characters in the config. Long lines overflow the editing box and it is very difficult to edit the entries, because the cursor position appears in places inconsistent with the text edited.

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

How reproducible:

Steps to Reproduce:
1. Make sure you are actually using the current GRUB version: grub2-install /dev/vda
2. Reboot
3. Press 'e' in the GRUB menu.
4. Use the cursor keys, try to get to the end of a line. Try editing something.
Actual results:
You won't reach the visible end of the line.
When you start typing something, you're actually editing text that does not lie exactly at the place where the cursor appears.

Expected results:
Consistently usable menu editor.

Additional info:
This may present a difficulty for debugging boot problems. We often need people to edit their kernel command line.
Fixing this post-release may be a problem, because AFAIK updating the grub2 package does not actually cause the new version to be used for the next boots.

I built grub2-2.0-0.23 from Fedora git and it seems to be fixed there. Can we get it into F17?

I forgot to mention that it affects the default installation. No configuration changes are necessary to reproduce the bug.

grub2-2.0-0.24.beta4.fc17 has been pushed to f17 stable - closing
