Comment 4 for bug 283520

Colin, I doubt that grub4dos supports UUIDs (haven't tested that), and even if it does, things will be a bit tricky, since

A) in case of updates we need to ship a new grub4dos (wubildr & co, which, by the way, might not be under /host)

B) wubi actually uses a first embedded menu.lst that uses heuristics to set the bootloader root and then loads a second menu.lst (the one visible as /boot/grub/menu.lst) within that root. The second menu.lst does not set root, it only sets the relative path, which is why we use "()". Such heuristic approach, while not bullet proof for obvious reasons, seemed to work ok also with multiple disks.

Hence i would suggest to stick with "root ()/relative/path" for this release.
