In this tutorial, we will set up a user level systemd unit for an unprivileged user. There are times when it's helpful to launch a user-level https://www.freedesktop.org/software/systemd/man/systemd.unit.html[systemd unit] without having to log in. For example, you may wish to launch a container that provides a network service or run an HPC job. For this setup, we will add the following to a Butane config:

	Launching a user-level systemd unit on boot
	Complete all the steps described in the xref:tutorial-setup.adoc[initial setup page] before starting this tutorial. Make sure you have create file `ssh-key.pub` following the instructions provided in the https://docs.fedoraproject.org/en-US/fedora-coreos/tutorial-setup/#_ssh_public_key[prerequisites] for the tutorial. We will use this key in the Butane configuration file that we are about to write.
	In this tutorial, we will set up a user level systemd unit for an unprivileged user. There are times when it's helpful to launch a user-level https://www.freedesktop.org/software/systemd/man/systemd.unit.html[systemd unit] without having to log in. For example, you may wish to launch a container that provides a network service or run an HPC job. For this setup, we will add the following to a Butane config:
	A user level systemd unit: `/home/sleeper/.config/systemd/user/linger-example.service`.
	Enable it as a user level systemd service.
	Setting up the systemd unit
	In this example, we will launch a systemd service for the user `sleeper`. First, let's create a user:
	variant: fcos version: {butane-latest-stable-spec} passwd: users: - name: sleeper
	This will also create the home directory for the `sleeper` user. Then we can add the systemd unit:
	variant: fcos version: {butane-latest-stable-spec} storage: files: - path: /home/sleeper/.config/systemd/user/linger-example.service mode: 0644 contents: inline: \| [Unit] Description=A systemd user unit demo [Service] ExecStart=/usr/bin/sleep infinity user: name: sleeper group: name: sleeper
	System services can be directly enabled in Butane configs but user level services have to be manually enabled for now:
	variant: fcos version: {butane-latest-stable-spec} storage: directories: - path: /home/sleeper/.config/systemd/user/default.target.wants mode: 0755 user: name: sleeper group: name: sleeper links: - path: /home/sleeper/.config/systemd/user/default.target.wants/linger-example.service user: name: sleeper group: name: sleeper target: /home/sleeper/.config/systemd/user/linger-example.service hard: false
	We set up lingering for the systemd user level instance so that it gets started directly on boot and stays running:
	variant: fcos version: {butane-latest-stable-spec} storage: files: - path: /var/lib/systemd/linger/sleeper mode: 0644
	As the following directories do not exist yet, we will have to create them to tell Ignition to set the right ownership and permissions:
	variant: fcos version: {butane-latest-stable-spec} storage: directories: - path: /home/sleeper/.config mode: 0755 user: name: sleeper group: name: sleeper - path: /home/sleeper/.config/systemd mode: 0755 user: name: sleeper group: name: sleeper - path: /home/sleeper/.config/systemd/user mode: 0755 user: name: sleeper group: name: sleeper - path: /home/sleeper/.config/systemd/user/default.target.wants mode: 0755 user: name: sleeper group: name: sleeper
	Writing the Butane config and converting to Ignition
	The final Butane config, stored in `user.bu`, will be:
