Description Kendrick Gay 2011-02-22 22:07:02 UTC
Description of problem:
When using grubby to parse boot parameters, it segfaults:

[root@gss-rhel5u5-32 ~]# grep -v ^# /etc/grub.conf

Segmentation fault

Version-Release number of selected component (if applicable):
mkinitrd-5.1.19.6-68.el5

How reproducible:
Setup dual boot system with Windows, then run "grubby --info=ALL" in RHEL

Steps to Reproduce:
1. Verify GRUB parameters for Windows in grub.conf
2. Run "grubby --info=ALL"
3. Observe segfault once parameters for Windows boot are accessed
  
Actual results:
grubby segfaults with Windows boot definitions in grub.conf

Expected results:
grubby ignores Windows boot definitions in grub.conf, or returns "non linux entry", as it does in later versions (grubby-7.0.x).
