When I did an install, 
I could use dnf, 
I don’t know if Postgres was a different version or installed differently, but the install methods have changed for it.

That was about as far as we got.

Note: I don’t usually use CentOS, if anything more is unusual I wouldn’t know.

I've played around with it on a VM, but nothing substantial.

I'm preparing to move my home servers over to it on the 1st. Can anyone
share any pitfalls they've had with it? Anything to avoid, or anything I
need to know, would be very helpful.

Home Servers will be running SabNZB, Sonarr, Radarr, and Plex.

Thanks!
