What's the difference between CentOS-8.1.1911-x86_64-boot.iso and CentOS-8.1.1911-x86_64-dvd1.iso?

I imagine the DVD is an installer which let's you choose which packages to install during initial installation. I might offer live boot, not sure.

The one that with -boot I imagine is a Live CD (or USB) to try the OS or maintenance/rescue of an existing system. Does this one also provide an installer for a minimal system so I don't have to use 7GB bandwidth and disk space? Where can I get such an ISO, I don't see a minimal intaller, just "-boot"

Solution 1:

The -boot images are designed for installation over the network, external disk or a file server, typically used to install large numbers of computers. Additionally, the package collections allow the select a minimal setup. More info can be found here
