Question

我的systemd输出有以下非常奇怪的错误：

5月26日10:21:11 ip-10-30-2-251.ec2.internal systemd [1]：[/ run / fleet / units / someservice.service：13]跟踪垃圾，忽略。 5月26日10:21:11 ip-10-30-2-251.ec2.internal systemd [1]：[/ run / fleet / units / someservice.service：14]缺少＆＃39; =＆＃39;。

这是在我运行以下服务时引起的：

任何想法为什么或如何解决此错误或可能导致错误的原因？

我想我听说某个地方有一条服务的最大行长。你有没有尝试将这个巨大的命令放入脚本并执行该脚本？如果这不起作用，您可以创建多个ExecPre语句并一次构造一个部分的脚本。然后您的Exec可以运行该脚本。如果您使用的是cloud-config，则可以使用'write_file'命令将脚本写入目标计算机。

github issue max length

2048是一条线的最大长度（反引号被消耗，你的命令是一条巨线）。
