Short answer: No, no, and no. ;)

Long answer: There are actually three questions you are asking here:

a) Should you expect something you built on one Linux distribution to 
run on another?

- The general answer to that is no, unless you take a lot of care in how 
you go about it.

b) Should we change the distribution used on x86 from Oracle Linux to 

- The general answer for that is no, as well, as the developers at 
Oracle maintaining the x86 port don't test on Fedora, so that would not 
work for us. The configuration options let you do that yourself in your 
own test environment, though, which allows different downstream 
distributors to test with their own systems.

c) Should we change the distribution used on x86 from a specific version 
tag to the latest tag?

- The general answer to that is no, too - as using the latest tag is not 
really good practice. See https://vsupalov.com/docker-latest-tag/ for an
