pacwrap 
A package management front-end which utilises libalpm to facilitate the creation of unprivileged, userspace containers with parallelised, filesystem-agnostic deduplication. These containers are constructed via bubblewrap to execute package transactions and launch applications.
This application is designed to allow for the creation and execution of secure, replicable containerised environments for general-purpose use. CLI and GUI applications are all supported*. Once a container environment is configured, it can be re-established or replicated on any system.
Goal of this project is to provide a distribution-backed alternative to flatpak with easily configurable security parameters.
* Some CLI-based applications, such as ncspot, require disabling termios isolation. This could allow an attacker to overtake the terminal and thus breakout of the container.
Example usage
To create a base container, execute the following command:
$ pacwrap -Syucb --target=base
Then to launch a shell inside of this container to configure it:
$ pacwrap -Es base
And finally, to install neovim inside of a fresh, aggregated container called editor:
$ pacwrap -Syucat editor --dep=base neovim
To update these containers just created in aggregate:
$ pacwrap -Syu
More advanced examples along with further documentation of configuration can be found further elaborated upon here.

Build requirements
A minimum version of Rust 1.72 is required to build with the following libraries fulfilled by your distribution:
libalpm=15, libseccomp, libzstd
Packaging requirements
The following Arch Linux packages (or your distribution's equivalent) are required for build-time artefacts:
bash, busybox, coreutils, fakeroot, fakechroot
Distribution support
Although this project aims to be distribution agnostic, at present only Arch-based distributions are supported. This project does aim, however, to be distribution agnostic, so in future it should be possible to support other distributions.
