systemd man page says:
systemd-fstab-generator(3) automatically adds dependencies of type Before= to
all mount units that refer to local mount points for this target unit.
So "Before=local-fs.taget" is the correct dependency for local mount
points, but we currently specify "After=local-fs.target", it should be
fixed.
Also replaced "WantedBy=multi-user.target" with "WantedBy=local-fs.target",
since .mount are not related with multi-user but depends local
filesystems.
