For the most part, using OSTree to install additional packages is [highly discouraged](https://docs.fedoraproject.org/en-US/fedora-coreos/faq/#_how_do_i_run_custom_applications_on_fedora_coreos). Instead, it's suggested to install and run things through [containers](https://docs.fedoraproject.org/en-US/fedora-coreos/running-containers/).
