Have a look into flatpak too, otherwise in the not-so-distant future the users could have a problem.

For Fedora, they are planning switching to Silverblue around Fedora 30 (atomic system, rpms still supported, but jumping around the hoops).

It will be interesting to see if Flatpak, Snap or AppImage ends up being the predominant force in the new wave of Linux packaging. Knowing Linux, users will probably expect projects to support all three. :-)
