Reload user related systemd configuration.

$ systemctl --user daemon-reload

Inspect service status.

$ systemctl --user status archivebox

● archivebox.service - archivebox service
     Loaded: loaded (/home/archivebox/.config/systemd/user/archivebox.service; disabled; vendor preset: enabled)
     Active: inactive (dead)

Enable and start service.

$ systemctl --user enable --now  archivebox

Created symlink /home/archivebox/.config/systemd/user/default.target.wants/archivebox.service → /home/archivebox/.config/systemd/user/archivebox.service.

Inspect service status.

$ systemctl --user status archivebox

Enable user lingering, so the user related systemd configuration will be read at boot.

$ loginctl enable-linger archivebox

Verify altered parameter.

$ loginctl show-user -p Linger $USER

Linger=yes

That is all.
