Aha .... good news to note that CentOS 7 has still life left on it until 2024.  I'm on CentOS 7.  When I tried CentOS 8, I found there were a few applications I had that didn't want to work with CentOS 8.  The first one was installation of python for running the speedtest script.  Then from one pre condition that was needed to another, there continued to be issues to contend with.  So I'm sticking with CentOS 7 for now.

(...)

Wait a minute!  Looks like CentOS 8 support has been cut down from 2029 to December 2021.  So CentOS 7 is going to be supported past CentOS 8 to 2024. Interesting. All the reason to use CentOS 7 in preference to CentOS 8.

The support for CentOS-7 was maintained because of the wider user-base and because of the date (2024 vs 2029!).. so No wonder there!

Hopefully by the time I have to change, there will be something better around.  Maybe Rocky Linux! Wonder whether there will be a huge learning curve involved and whether it will be an easy migration from CentOS 7?  Maybe @fChk will know?

Theoretically it shouldn't!.. It's basically the same code source compiled under a different label. That's all there is to it.

For the migration, that's up to the new team: they can make it as easy as they can and/or wish to be user-friendly.. so, in other words, it will depend on how much financial backup they will have to sustain their efforts/work.

Having watched FOSS-projects for more than 2 decades, the rule of thumb is this: The more financial incentive they will have, the more user-friendly they would wish to be!
