Subject: systemctl: Only wait when there's something to wait for.
X-Git-Tag: v240~930
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=46f2579c2ac9f6780d5afec1000764defc6b581e;p=platform%2Fupstream%2Fsystemd.git

systemctl: Only wait when there's something to wait for.

Tested:
- `systemctl --wait start i-do-not-exist.service` does not wait.
- `systemctl --wait start i-do-not-exist.service valid-unit.service` does.
