QA:Testcase Dracut switch to host-built ramdisk

Description

This test case is intended to validate using a host-built dracut generated ramdisk image on system currently using a locally-built mkinitrd generated ramdisk image.

How to test

1. On an already installed system (e.g. Fedora 11), Confirm that the kernel provides a dracut host-built ramdisk image

   rpm -qf /boot/vmlinuz-$(uname -r) -l | fgrep -q initrd-generic \

   && echo "OK. Dracut ramdisk already provided by kernel rpm" \

   || echo "Bad. No dracut ramdisk provided by kernel rpm"

2. Tell your bootloader to use the dracut ramdisk

   grubby --make-default --title "dracut-test" \

   --add-kernel /boot/vmlinuz-$(uname -r) \

   --initrd /boot/initrd-generic-$(uname -r).img \

   --copy-default

3. Now reboot the system

Expected Results

1. This test is only valid on a system that does provide a dracut ramdisk image with the kernel rpm. To confirm, you should see

   OK. Dracut ramdisk already provided by kernel rpm

2. A new grub boot entry is added that uses your existing kernel, and the dracut ramdisk
3. The system boots normally. There should be no difference between booting the locally-built mkinitrd ramdisk image and the host-built dracut ramdisk image.
