It
persists, but only until some _inevitable_ event occurs, as we both described:

does not persist. Every kernel addition or removal…

Such postprocess is pointless here. The bulk of my custom.cfg entries use
LABELS.
None use UUIDs. And, grub.cfg entries are ignored, displayed onscreen as
available
selections only after scrolling past 20-30 or more custom.cfg entries:
