Description of problem:
The GRUB setting for timeout do not allow changes on firstboot.
The installer must must into rescue mode to modify grub if debug changes are needed.
Another issue is the the kernel commands entered during the install are not copied to the kernel command.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Preform an basic install on any x86_64 system
2. Attempt kernel command setting
In my case pcie_aspm=off
3. Attempt to change the command to pcie_aspm=on on firstboot
pcie_aspm is not on the kernel comman line in /boot/grub/menu.lst
The setting of timeout= 5 or more by default so that the user can stop grub to make changes.
Example of grub setting
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/sda3
# initrd /initrd-[generic-]version.img

Since we have another bug filed later but was cloned from one filed earlier just on this situation, I'm going to dupe this one to that one.
