我正在尝试systemd-journald首次配置额外的 /log 命名空间（在 Debian bookworm 上）（因为这似乎是为不同的服务配置不同日志存储量的唯一可能性）。
我已经创建并添加了设置。/etc/systemd/[email protected]/etc/systemd/system/[email protected]LogNamespace=postfix
当我启动 Postfix 实例时，一开始一切都按预期运行：实例systemd-journald已启动并在 下创建其目录和文件/var/log/journal。但 31 秒后，systemd-journald实例退出（代码为 0），原因不明。Postfix 实例（这是使用此日志命名空间的唯一服务）继续运行。没有错误消息，只有：
systemd[1]: [email protected]: Deactivated successfully.
这是在主日志命名空间中。它本身只记录以下内容：
systemd-journald[1274]: Journal started
systemd-journald[1274]: System Journal (/var/log/journal/6aca95cee9e8c625f75e5f2865f56978.postfix) is 8.0M, max 1.4G, 1.4G free.
systemd-journald[1274]: Journal stopped
如果手动启动也会发生这种情况[email protected]（无论 Postfix 是否正在运行）。
这似乎不是由外部引起的。strace没有显示信号或类似的东西：
