In elementary OS, we're building our images with some flatpaks pre-installed. To do this, we run noninteractive `flatpak install` commands in the chroot as part of the build scripts. We've bumped into some build failures recently after switching to a version of flatpak with malcontent support built in.
After some debugging, it turns out installations are failing the parental controls checks with errors like `Failed to install org.gnome.Epiphany: Could not connect: No such file or directory` message. I'm assuming this is a failure to connect to the system bus in this method (since there isn't one in the chroot).
Is it reasonable to assume that UID 0 should be allowed to install whatever they want regardless of parental controls? I believe this would fix our issue too.
