Description of problem:
With the below grub.conf, rpm -i of kernel RPM hangs at post-install.  Deleting
the line beginning "#password" fixes the problem.


Version-Release number of selected component (if applicable):
Note: The system where I discovered this is RHL 7.2, but I would guess it
happens with all the current errata kernels.


How reproducible:
Always

Steps to Reproduce:
1. Install attached grub.conf
2. rpm -i latest kernel rpm
3. observe hang
    

Actual Results:  rpm hangs.  When killed, grub.conf is unmodified.

Expected Results:  rpm finishes and grub.conf is updated.

Additional info:
The grub.conf file in question:
