(i'm free associating here so, be warned ...) i've designed and delivered a *bunch* of linux/linux-related courses, and one of the things that seems to really, really, really set the stage properly early on is to list the components to be covered, and map those components *specifically* to the red hat/fedora packages that provide them. it may sound weird but, in the relevant courses, students seem to grasp the "big picture" more quickly if one not only lists the concepts to be covered, but maps that to actual fedora (my OS of choice) packages, along with what each package provides. let me give an example. if i'm going to teach a course on containers on fedora (which is my plan), it would be easy to just: $ sudo dnf group install --with-optional "container management" and go from there. but my experience is that it's clearer if one starts with the *minimal* set of packages to get started and, as the class progresses, one by one, installs each additional package only when necessary, while explaining what that new package brings to the table. so, after displaying the various components of container technology, i would start with only podman (and, sure, podman-docker) installed, and cover what that allows one to do. once that's done, introduce and install "buildah", and work with that. after that, skopeo, i guess, and so on, and so on. mapping each feature to a separate package really drives home the idea that these are different features that can be installed and worked with separately. over the next day or two, i'm going to flesh this out and put it all on a wiki page to make it clearer. i guess what i'm talking about here is explaining the entire container "ecosystem", and mapping that to the (fedora/RH) packages that support it. thoughts? rday
