So all block device mounted by systemd-udevd is unvisible for host. I don't know why. And is there any bad effect, if I change slave to shared ? Thanks for your help.

And is there any bad effect, if I change slave to shared ? Well, we generally try to run all our services with sandboxes that are as tight as we can make them. udev can run arbitrary stuff from its rules hence the sandbox can't be made too tight unfortunately. MountFlags=slave is essentially a sandboxing setting: it detaches mount() operations done within the service from the rest of the system. While udev rules can do pretty much everything, we do know that doing mount operations themselves is not the best of ideas, and there are better approaches. That's because udev rules should be quick, and mounting isn't necessarily (in particular on dirty fs). Specifcally, there are three schemes that are much preferable: 1. Use TAG+="systemd", ENV{SYSTEMD_WANTS}+="foobar.mount" in udev rules to asynchronously pull in mount units from udev rules. 2. Invoke "systemd-mount" from udev rules, which will spawn transient automount and mount units for devices. This is generally the best way in particular in embedded applications to deal with hotpluggable media. It optionally runs fsck before mounting for you, and it it uses automounts for keeping the actual window when a device is mounted as brief as possible, in order to maximize the chance that the file system remains in a fully clean state, since it's essentially unmounted whenever idle. If you have hotplug media this means you get the best chance of leaving the fs in a clean state, and getting it back into a clean state if it evers gets into an unclean state. 3. Use a daemon such as udisks to manage hotplugs of devices. That all said, you can also deviate from upstream and simply drop the MountFlags=slave, but of course, this means you lose compatibility with upstream on this.
