+Subject: ostree-install: allow configuring additional depenencies for runroot
+
+
+A lorax template used for the ostree-installer might need an additional
+package dependency (e.g., flatpak to embed a flatpak repository) - add
+a config key 'extra_runroot_pkgs' to the ostree installer configuration
+to allow supplementing the set of packages installed into the runroot.
