rd_NO_LUKS says that there are no encrypted filesystems. We *strongly*
prefer to label our filesystems.

Finally, if you can see it running via linux rescue, I'd go with Les'
thought: boot that way, chroot to /mnt/sysimage, and first do a
grub-install. If that doesn't solve it, then try the rebuild of initrd.

Oh, and check /mnt/sysimage/etc/fstab
