distrobox: Tool for creating one-off containers of a different Linux distro.
container: A virtual OS environment that runs on your computer, but doesn't know that it's running in your computer. It's not the same as a VM or emulator.
flatpak: A tool designed by RedHat for running sandboxed Linux programs in any environment. Flatpak can either refer to the system as a whole (eg: "You need to install flatpak on your machine to use our tools") or an individual program packaged for the flatpak system (eg: "You must download the latest flatpak of Firefox").
AUR: The Arch User Repository. A collection of installation scripts to add software to Arch Linux. These scripts are not owned or maintained by anyone officially affiliated with Arch, so you can find AUR packages for almost anything.
So, the comment becomes: Stick it in a dedicated environment designed to run Debian. Then package it so anyone can run it. Then make it easy for anyone running Arch Linux to install it.
I know all the words that aren't nouns in that sentence!

flatpak… is unrelated to redhat, at least at the moment
it was initially made as a side project by a person who worked at red hat on containers, nowadays it's developed by freedesktop.org
