Comment 5 for bug 1563590

> /bin/systemctl link '/var/lib/juju/init/jujud-machine-0/jujud-machine-0.service'
> /bin/systemctl enable '/var/lib/juju/init/jujud-machine-0/jujud-machine-0.service'

This is redundant. Either use link like that and enable with just "jujud-machine-0.service" (link already created the symlink in the standard paths), or just directly enable the unit with full path and skip the link. However, this currently fails due to https://github.com/systemd/systemd/issues/3010, which is an actual regression.
