I suspect this never worked, but that before the error was silently
ignored.  In my case, I had:

  (swap-devices '("/dev/disk/by-label/jojen-swap"))

and /dev/disk went away at some point due to another problem.  For a
long time, I simply had no swap.  With the dmd -> shepherd transition,
it started causing a fatal error during boot, leading to a kernel panic.
Unfortunately, the error message scrolled off the screen very quickly,
obscured by a useless kernel backtrace.
