Re: systemctl restart sddm
Looking at: [1](https://wiki.archlinux.org/index.php/Rng-tools), and then
following to: [2](https://en.wikipedia.org/wiki/
Hardware_random_number_generator), one can think that rng-tools uses: [3]
(https://en.wikipedia.org/wiki/RdRand).
But it might not be so, since [2] says: "The RdRand opcode will return values
from an onboard hardware random number generator. It is present in Intel Ivy
Bridge processors and AMD64 processors since 2015", and IvyBridge started in
2012, and rng-tools code is very, very old (but there is some overlapping
time, possibly).
Therefore believing that rng-tools uses RdRand's CPU hardware random generator
instruction, might be pure misconception.
Consequently, haveged seeming much newer and maintained, it is in my opinion
the best choice.
Thanks
