systemd 计时器单元启动其他几个服务

systemd 计时器单元启动其他几个服务

我有一个 systemd 计时器,每 5 秒启动一个关联单元。这按预期工作(它会向日志发送垃圾邮件,但这是另一个问题),但它显然还启动了一些其他通常不应启动的 systemd 单元。这些是我的单位文件:

/etc/system.d/system/make_temps.service

[Unit]
Description=Puts all the temperatures in one file

[Service]
LogLevelMax=6
Environment=SYSTEMD_LOG_LEVEL=debug
Type=oneshot
ExecStart=/usr/local/bin/make_temps

/etc/systemd/system/make_temps.timer

[Unit]
Description=Timer for unit putting the temperatures in one file

[Timer]
OnActiveSec=0sec
OnUnitActiveSec=5sec
AccuracySec=500msec

[Install]
WantedBy=timers.target

我用它来为另一个程序准备一个文件: 思凡。我提供这些信息只是为了确定,尽管我认为这并不重要。

当我使用journalctl检查日志时,我得到以下输出:

为什么 服务 systemd-firstboot.service、、、、、、、、、、 启动 ? systemd-fsck-root.serviceldconfig.service​ ​ ​ ​systemd-boot-system-token.servicesystemd-hwdb-update.servicesystemd-journal-catalog-update.servicesystemd-machine-id-commit.servicesystemd-sysusers.servicesystemd-update-done.service

不得不说,这些信息并不是每次都会出现,而是几乎每次都会出现。我认为它相关的原因是,在我的其他系统上,这些消息不会出现(因为我不使用这些单元),并且当我停止计时器单元时,其他服务也不会被触发。我不知道为什么会发生这种情况,并且非常感谢每一个提示。

我在内核上使用 Arch Linux 5.5.13-arch2-1,我的 systemd 版本是:

systemd 245 (245.4-2-arch) +PAM +AUDIT -SELINUX -IMA -APPARMOR +SMACK -SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN2 -IDN +PCRE2 default-hierarchy=hybrid

如果我可以提供任何其他信息,或者这不是发布此信息的正确位置,请告诉我。
