You can actually do that by using "chroot" from a rescue CD. I usually want to do that on my systems, when I clone from a machine with hardware RAID to a machine on which I will use software RAID. After copying the image (using dd or whatever), I mount the partitions under /mnt/sysimage and /mnt/sysimage/boot, then I do a chroot /mnt/sysimage, and then I do mkinitrd, using -f to overwrite the old one and specifying the exact version of the kernel grub is configured to boot with. For adding/removing drivers, mkinitrd works like a charm. For renaming VGs, I don't know if it would detect them right. As it is on the destination machine, I'm guessing it would, but as I didn't really test it, I cannot be sure. Anyway, if you get to it and test mkinitrd to correct the name of the VGs inside initrd and it works, let us know! Thanks, Filipe
