For OSs other than the above:
Delete the root specification in the configuration that you copied in
step 21. If you are using a Xen kernel, delete the root device

Specify the initial RAM disk image file created in step 19 for initrd
contained in the boot loader configuration file.
Change the initrd specification in the configuration that you copied in
step 21. If you are using a Xen kernel, change the initrd file name
specified in module to the initial RAM disk image file you created in step
19. For details on Xen kernels, see Table 3-61 Xen Hypervisor Operating
Environments Supported by HDLM on page 3-88 .
Keep in mind that the specification method for initrd differs depending
on the boot loader.
If any options have been specified to suit the user environment, take care
not to delete those options.
