From looking at the script that builds the initalrd image, it looks like the volume group for the root directory is part of the information in the image. That would prevent using the same initrd image for both installations. But this is my first installation using LVM, so I do not claim to be an expert. Before LVM, it was easy to change the root partition in the Grub command line. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
