[fedora-arm] Random entropy difference between F26 workstation and minimal server

[Robert Moskowitz]

I use:

cat /proc/sys/kernel/random/entropy_avail

To check on the amount of entropy for creating random stuff like 
keypairs with openssl or random nonces and keys for TLS..

I am using a Cubieboad2.

With Fedora-Xfce-armhfp-26-1.5-sda.raw.xz I was seeing numbers in the 
3,000.  I don't have that image running right now to get an actual number.

I just built a system with:  Fedora-Server-armhfp-26-1.5-sda.raw.xz

I am seeing numbers only in the mid 800s:

[root@C2 ~]# cat /proc/sys/kernel/random/entropy_avail
866
[root@C2 ~]# cat /proc/sys/kernel/random/entropy_avail
803
[root@C2 ~]# cat /proc/sys/kernel/random/entropy_avail
828


What is different between these two images?  It is the same Cubieboard.

I have had to install haveged on my Centos7-arm images to get decent 
entropy.

I have also installed rng-tools with some success, but not as much as 
haveged.

thanks

Bob
