Comment 8 for bug 367260

Hm, maybe I was a bit too eager and fast changing the status. What I meant was that /dev/random needs noise to generate random numbers:

"When the entropy pool is empty, reads from /dev/random will block until additional environmental noise is gathered." (from http://en.wikipedia.org/wiki//dev/random)

So it actually makes sense that you should use /dev/urandom for this task. Since we are "only" talking about encrypting a swap partition, I think this is safe enough. But please correct me on this, if I'm wrong.
