Question

我在嵌入式系统中工作，我们正在从upstart迁移到systemd。我试图在rootfs中为/ dev编写.mount文件。但这失败了。有人可以帮忙吗？

[Unit]
Description=/dev Directory
Documentation=man:hier(7)
Documentation=http://www.freedesktop.org/wiki/Software/systemd/APIFileSystems
DefaultDependencies=no
Conflicts=umount.target
Before=local-fs.target umount.target

[Mount]
What=tmpfs
Where=/dev
Type=tmpfs
Options=mode=1777

我的文件名为dev.mount。

我收到以下错误 Cannot add dependency job for unit dev.mount, ignoring: Unit dev.mount failed to load: Invalid argument

Answer 1

摘自文档 systemd.mount

某些文件系统具有特殊语义作为用于内核到用户空间和用户空间到用户空间接口的API文件系统。其中一些可能无法通过安装单元进行更改，也无法禁用。

另见： API file systems

无法在systemd中为/ dev创建自定义安装点
