systemctl output sent to stderr which may not help other software to detect whether starting of the service was failure or success?

Issue

• The output of 'systemctl enable ' is sent to standard error, although the command completes successfully (output: ln -s '/etc/systemd/system/.service' '/etc/systemd/system/multi-user.target.wants/.service'). This causes problems when automation tools use the output channel as an indicator about failure or success. i.e with BMC BladeLogic.
