Note, `systemd-analyze foo@.service --instance=hoge` is equivalent to `systemd-analyze foo@hoge.service`. But, the option may be useful when e.g. passing multiple template units that have restriction on their instance name: ``` $ ls template_aaa@.service template_bbb@.service template_ccc@.service $ systemd-analyze ./template_* --instance=hoge ``` Without the option, we need to embed an instance name into each unit name, so cannot use globs. Prompted by #33681.
