Comment (by Thorin):

 I have done more testing, and improved the output in my test: including a
 red info if I haven't seen the hash before. I have now found that TB on
 Linux actually has more entropy than originally thought. After testing 5
 distros (a mix of flavors and architecture) I have 3 distinct Linux
 buckets (it's not enough to distinguish the actual platform, at least not
 in all cases, yet). I will be adding more distros to investigate further.
