Use > /dev/device rather than UUID= ? But the <device> varies by board. I did a basic google search and found that something like: uuidgen along with sudo tune2fs /dev/sd__ -U ______ Of course you have to provide the device and uuidgen output. would do the trick. Should be a way to piple uuidgen output into tune2fs. Still how to programatically edit /etc/fstab. And I should point out that this can be done on a live system (with careful editting of fstab!). sudo blkid will give you what you currently have so you can correctly do this. And there might be better ways...
