Automount Samba shares on Debian Buster

Debian Buster requires the option x-systemd.automount in fstab to mount SMB shares. So my fstab line looks like this:

//<SERVER_IP>/video      /home/shares/video   cifs    vers=3.0,rw,user,credentials=/home/<USER>/<CREDSFILE>,uid=<USER>,gid=<USER>,x-systemd.automount,_netdev  0       0

Magically, this mounts the share when you first access it rather than from boot time.
