I thought it may be worth writing about the dnf-local plugin. It is something I’ve used now since around the Fedora 28 days. I don’t know if it is widely used but it has proven very useful to me as I have a dozen or so Fedora machines that I care for.
We could cover the installation and configuration of the plugin, how it is used and what the benefits are, especially for those on limited bandwidth or monthly useage caps.
I would consider authoring the article and would provide a screenshot or two of my own terminal as DNF is being used.
