Thank you very much. It dose work. Would you tell me that how the '--no-block' works,
I doesn't deeply understand the interpretation in https://www.freedesktop.org/software/systemd/man/systemd-mount.html#SYSTEMD_MOUNT_OPTIONS= And why systemd-mount can solve the problem brought by MountFlag=slave. Best Regard, Hongzhi On 2018年02月28日 03:02, Andrei Borzenkov wrote:

In your reply, you told me to invoke "systemd-mount" from udev rules.
