I think the root= here will be overridden by the flash-kernel hook in
the initrd (the script I pointed to earlier). A better bet might be to
hack that to override the root to /dev/VG01/root or to fiddle the
flash-kernel option which makes it do that
(Bootloader-sets-Incorrect-Root on Jessie, something else on Wheezy
which I can't remember)
