That won't necessarily work. The last music-hosing bug totally screwed up the filesystem. It wasn't that simple.

Unless it was something involving unmounted writes, and depending on how you do those, even then, there's still limited damage you can do that the kernel can't be modified to simply not allow. Doesn't really do much good for testing, of course.

But then, that's what backup empegs are for. This one ate itself? Pull out the spare, plug it in, keep driving.
