Systemd Rolls Out Its Own Mount Tool
The systemd-mount command is similar to the traditional mount command on Linux systems but with some differences.
Lennart describes in the documentation for systemd-mount, "instead of executing the mount operation directly and immediately, systemd-mount schedules it through the service manager job queue, so that it may pull in further dependencies (such as parent mounts, or a file system checker to execute a priori), and may make use of the auto-mounting logic."
Systemd-mount was added to systemd Git yesterday and will be part of the upcoming systemd 232 release. This is part of their greater work on transient mounts and automounts within the systemd scope.
