我正在嵌入式系统中工作，我们正在从 upstart 迁移到 systemd。我正尝试在 rootfs 中为 /dev 写入 .mount 文件。但这失败了。有人可以帮忙吗？

[Unit]

[Mount]
What=tmpfs
Where=/dev
Type=tmpfs

我的文件名是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
我在 stack overflow 上发过同样的问题。如果是错的，我准备删除那个或这个。 https://stackoverflow.com/questions/33242232/cannot-create-custom-mount-point-for-dev-in-systemd
