Comment 4 for bug 1397652

Yeah, indeed. https://en.wikipedia.org/wiki//dev/random also describes this aspect in more detail (but of course it's not a reference to rely on). Unfortunately the FHS (http://www.pathname.com/fhs/pub/fhs-2.3.html#DEVDEVICEFILES) makes no statement about this at all.

I added a manpages tasks for possibly updating the manpage if the kernel defaults are deliberate.
