yeah, that kind of speaks for itself how the by-{uuid,id,label} link can shift
between sda <-> sda1.

Not that I know of. It's pretty much like on x86, with sector 0
containing a few boot bytes to load "something else", irrespective
of a logical partitioning scheme superimposed on top.

You could move the disk blocks down the line (intricate dd_rescue
operations) and modify the partition table to match it,
moving /boot so it does not start at 0.
