There are two 'root' variables involved: 1) GRUB's 'root' variable, its base for filesystem operations 2) The root= parameter passed to the Linux kernel, which identifies the desired root filesystem Robert is talking about 1), but whether you use an initrd/initramfs is only relevant to 2). -- Colin Watson [cjwatson@ubuntu.com]
