so there are mitigations - the question really is: why hasn't redhat made these

The challenge is this is so system dependent.  Some are just fine with stock 
install.  Others need rng-tools.  Still others need haveged.  If Redhat were to 
do anything, it would be to stop making the default cert during firstboot.  
Rather spin off a one-time process that would wait until there was enough 
entropy and then create the default cert.  Thing is I can come up with 
situations were that can go wrong.

There are a lot of best practices with certificates and crypto that are not 
apparent to most admins.  I know some things for the crypto work I do (I am the 
author of the HIP protocol in the IETF).  There is just not one size fits all 
here, and people need to collect clues along with random entropy....
This default cert is not valid anyway and as random source they use:
Not valid in what way?  Yes the Subject and Issuer names are dorkie, but how 
are they not valid?

Not valid in terms of validation (PKI), not equal with verification in terms of "it 
works".

Oh, and in my 8 years with Verizon, I worked with the Cybertrust PKI team. And I am the author of the Bridge CA model used in the US Fed PKI, the BioPharm PKI and a few others.

I despair about what it costs to do decent Identity management. And how meaningless much of it still is.
