So we're able to generate correct root= for kernel command line but can only guess which names you would need for grub's set root=. The solution we're going for is to have UUID of fs stored in grub.cfg and go through all partitions on boot and find the right one nd set it to root variable. As for passing root= kernel parameter the decision of using device name or UUID= is based on heuristics (sigh) but you can disable them altogether in /etc/default/grub:
