I wonder if this is where I got the idea that some machines don't have a
predictable hardware discovery sequence? Or is there some hardware that
doesn't have a predictable sequence? I know that adding and removing
hardware can upset things royally and that hardware that suddenly springs to
life while the system is running is also "interesting" but is there anything
that really does vary from boot to boot?
