The aforementioned describe how flatpak supports P2P installations across a LAN. Does dnf5 provide equivalent functionality (and by default)?
I ask because:
I frequently want to install an .RPM package that another machine in my LAN has installed, but does not retain the .RPM for (unless, like on AOSP, the original installer is always retained).
On one of your machines you may configure it to retain the downloaded rpms and act as a local repo. It does not necessarily need to be a full mirror repo, but then would have the currently installed software from which the other machines may draw.
