[Beowulf] flatpack

So in a nut shell this is taking dockerization/ containerization and making it more for the every day Linux user instead of the HPC user?

It would be interesting to have a distro built around such a setup.

It seems that way, with an element of sandboxing to try and protect the user who is using these packages.  The Debian/Ubuntu package describes it thus:

  Flatpak installs, manages and runs sandboxed desktop application bundles.
  Application bundles run partially isolated from the wider system, using
  containerization techniques such as namespaces to prevent direct access
  to system resources. Resources from outside the sandbox can be accessed
  via "portal" services, which are responsible for access control; for
  example, the Documents portal displays an "Open" dialog outside the
  sandbox, then allows the application to access only the selected file.
  Each application uses a specified "runtime", or set of libraries, which is
  available as /usr inside its sandbox. This can be used to run application
  bundles with multiple, potentially incompatible sets of dependencies within
  the same desktop environment.
  This package contains the services and executables needed to install and
  launch sandboxed applications, and the portal services needed to provide
  limited access to resources outside the sandbox.

There's also more about it here:


The downside (from the HPC point of view) is that these binaries will need to be compiled for a relatively low common denominator of architecture (or with a compiler that can do optimisations selected at runtime depending on the architecture).

All the best,
