Bug#880158: systemd-container: machinectl incorrectly reports "No machines." when using --no-legend

[David Preece]

Package: systemd-container
Version: 232-25+deb9u1
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I am running containers launched with systemd-nspawn. They show up in 'machinectl' just fine.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Running machinectl with the --no-legend flag causes it to report "No machines." *after* the actual list of machines.

   * What was the outcome of this action?

admin at ip-172-31-15-145:~$ machinectl
MACHINE                    CLASS     SERVICE        OS     VERSION ADDRESSES
ctr-emVnH3DhH3rStx3g78sGyh container systemd-nspawn alpine 3.6.2   10.1.16.204...

1 machines listed.
admin at ip-172-31-15-145:~$ machinectl --no-legend
ctr-emVnH3DhH3rStx3g78sGyh container systemd-nspawn alpine 3.6.2   10.1.16.204...
No machines.

   * What outcome did you expect instead?

That "No machines." would not be orinted.
