    # Distro configuration matrix
    #
    # Each build is run in a Docker container specific to the distro.
    # When adding a new distro, handle the dependency installation in
    # `ci/gh-install.sh`. The matrix configuration options are:
    #
    # name: A friendly name to use for the job.
    #
    # image: The Docker image to use.
    #
    # container-options: Additional Docker command line options.
    #
    # pre-checkout-setup: Commands to run before the git repo checkout.
    #   If git is not in the Docker image, it must be installed here.
    #   Otherwise, the checkout action uses the GitHub REST API, which
    #   doesn't result in an actual git repo. A real git repo is
    #   required to checkout the submodules.
    #
    # extra-packages: Packages to install in addition to those in
    #   `ci/gh-install.sh`. This can be used to support features from
    #   additional `configure` options.
    #
    # configure-options: Options to pass to `configure`.
    strategy:
      # Let other configurations continue if one fails.

            # FIXME: The ubuntu-latest VMs are currently based on 20.04
            # (focal). In focal, libseccomp2 doesn't know about the
            # close_range syscall, but g_spawn_sync in impish tries to
            # use close_range since it's defined in glibc. That causes
            # libseccomp2 to return EPERM as it does for any unknown
            # syscalls. g_spawn_sync carries on silently instead of
            # falling back to other means of setting CLOEXEC on open
            # FDs. Eventually it causes some tests to hang since once
            # side of a pipe is never closed. Remove this when
            # libseccomp2 in focal is updated or glib in impish handles
            # the EPERM better.
