A patch [0] that added Fortuna [1] support to Linux was offered over 10 years ago. Fortuna specifically addresses the problems of entropy estimation that the grandparent comment brings up: "making any kind of estimate of the amount of entropy is extremely difficult, if not impossible. It depends heavily on how much the attacker knows or can know, but that information is not available to the developers during the design phase." "Fortuna solves the problem of having to define entropy estimators by getting rid of them." 0: https://jlcooke.ca/random/ https://jlcooke.ca/random/ 1: https://www.schneier.com/cryptography/paperfiles/fortuna.pdf https://www.schneier.com/cryptography/paperfiles/fortuna.pdf
