Service 当启动/停止失败时，systemctl是否应显示输出？

我已经用谷歌搜索了我能想到的这个问题的每一个变体，但我只是得到了关于失败服务的问题，而不是关于systemctl如何对待它们的问题。我有一个作为init.d脚本运行的服务。我们现在用的是systemctl，很好。我创建了一个服务文件，它是systemd sysv generator自动生成的文件的一个稍加修改的版本。对于ExecStart和ExecStop，它调用一个bash脚本，如果启动/停止成功，则返回0；如果启动/停止失败，则返回非零

我知道如果“systemctl启动/停止”成功，则不会有任何输出。但是如果两个调用都失败了，我也不会得到任何输出。systemctl start/stop命令的返回代码始终为0，即使源脚本的返回代码不是。很明显，它确实失败了，因为当我运行status命令时，它显示为failed

这是预期的行为吗？除非运行单独的status命令，否则它是否应该给出某些失败的指示？如果它不应该这样做，我怎么能让它表明发生了故障

服务文件如下

[Unit]
SourcePath=/my/service/script.sh

[Service]
Type=forking
Restart=no
TimeoutSec=5min
IgnoreSIGPIPE=no
KillMode=process
GuessMainPID=no
RemainAfterExit=yes
ExecStart=/my/service/script.sh start
ExecStop=/my/service/script.sh stop

CentOS 7号，这里很好。也许再检查一下script.sh是否真的返回了非零

$pwd
/etc/systemd/system
$cat me.service
