That's always been true.  glabel only notices a changed label on taste
events, and those only happen when the underlying provider is either
initialized for the first time, or closed after being open for write.

As root, you can force a retaste with
	: 3>/dev/acd0

(That's the ':' command, not punctuation.  Any command would do.)
