Verbose startup on MacOS X

I’m a bit torn here. I like to know what my computer’s doing when it’s starting up, but I also like the calm serenity of the Grey Screen Of Boot that my Mac gives me. I know that I can press command-V on startup to get the verbose unixey startup, but I’m always too early, or too late, or something. I’ve only managed to get that working a few times.

But now, I just discovered this:

sudo nvram boot-args=“-v”

This will make it always boot up in verbose I’m-a-geek mode. I imagine running the command again with boot-args=“” would unset it, but don’t quote me on that.
