The systemd init manager support mount point configuration via mount units and /etc/fstab. 'Mounts listed in /etc/fstab will be converted into native units dynamically at boot and when the configuration of the system manager is reloaded. In general, configuring mount points through /etc/fstab is the preferred approach.' [1] Read mount points from /etc/fstab to determine dynamic mount units.
