Description
Disabling the startup chime has stopped working with Yosemite, I'm afraid. Or at least I can't make it work.
Running sudo nvram SystemAudioVolume=" " works as expected since the new value is reflected in sudo nvram -p. However, upon reboot, the startup chime comes to greet me as usual.
Running sudo nvram -p afterwards shows that the value has gone back to the default L, so it would seem as if Yosemite resets the value to its default on reboot and before the chime, so the change is never made effective.
I've found this question in AskDifferent, but they haven't concluded anything. Maybe somebody here faced the same problem with better luck?

Research direction
Start by reproducing the Yosemite behavior with sudo nvram SystemAudioVolume=" ", rebooting, and checking sudo nvram -p afterward. Compare the result with the linked AskDifferent discussion; done means establishing whether Yosemite resets the value and identifying a confirmed way to prevent the startup chime or documenting that none is known.
