Package Manager (apx)

apx is the Vanilla OS package manager. It’s meant to be easy to use, but also powerful with support for installing packages from multiple sources without altering the root filesystem.

How it works

apx introduces a whole new paradigm in package management. The idea is to use your system only as a box for storing your files, leaving it clean of packages and limiting the risk of breaking due to incompatible, poorly constructed or conflicting packages.

This is done by installing software inside one or more “managed” containers, which are fully managed by apx and have restricted access to your system’s resources, while still being able to use the same drivers, display server, etc.

Your home directory is mapped inside the container, so you can access your configuration files, preferences and other vital data needed by the installed packages, as well as being able to access your own files from the installed software, e.g. by opening a file in LibreOffice.

Host system

While installing software on the host is against the ideology of the project, there are cases where this cannot be avoided, for example when you need to install a kernel module.

In cases like this, you can use the command abroot exec apt install <package_name>* to bypass the container and install directly on the host, but be aware that this is not recommended.

Multiple sources

By default, apx provides a container based on your Linux distribution (Ubuntu 22.10 for Vanilla OS 22.10) and wraps all commands from the distribution’s package manager (apt for Ubuntu).

Nevertheless, it is still possible to install packages from other distributions using other package managers, for example, using the --aur flag, a second container based on Arch Linux will be created. Here, apx will manage software from the AUR (and Pacman), always integrating it with the host system.

For quality control and testing needs, we have chosen to limit this feature to specific implementations. Currently, only the --aur flag is supported, but we are planning to implement support for the Nix package manager as well.

The name

The name apx comes from apt (Advanced Packaging Tool), the package manager used by Debian and its derivatives, and X, which should be seen as 2 lines (host and container) overlapping, where the container is on top, meaning it is on top of the host system.
