a good description of how they contribute, under modest work loads:

"The Linux Random Number Generator"
- https://pthree.org/2014/07/21/the-linux-random-number-generator/
'''
First thing is first- both /dev/random and /dev/urandom are fed data
from the same CSPRNG. Let me repeat that, with a bit more emphasis:
Both /dev/random and /dev/urandom are fed data from the same CSPRNG...
'''

haveged and rngd contribute to both pools, per the discussion re "true
random" sources "reseeding" the CSPRNG.
