flatpak

• https://docs.flatpak.org/en/latest/introduction.html

a system for building, distributing, and running sandboxed desktop applications on Linux.

Flatpak allows applications to be installed and run on virtually any Linux distribution. This includes non-GNU distributions, systemd-free distributions, distributions with a read-only operating system (OS), and various architectures without the developer needing the relevant hardware on hand.

Rootless install: elevated privileges are not required when installing a Flatpak application or a runtime.

Flatpak is built on top of a technology called OSTree, which is influenced by and very similar to the Git version control system.
