Just a quick comment:
.include is discouraged nowadays. The recommended way is to use drop-in
snippets. So, please don't use ".include" anymore!
As for drop-ins, see [1]
* Configuration of unit files may now be extended via drop-in
files without having to edit/override the unit files
themselves. More specifically, if the administrator wants to
change one value for a service file foobar.service he can
now do so by dropping in a configuration snippet into
/etc/systemd/systemd/foobar.service.d/*.conf. The unit logic
will load all these snippets and apply them on top of the
main unit configuration file, possibly extending or
overriding its settings. Using these drop-in snippets is
generally nicer than the two earlier options for changing
unit files locally: copying the files from
/usr/lib/systemd/system/ to /etc/systemd/system/ and editing
them there; or creating a new file in /etc/systemd/system/
that incorporates the original one via ".include". Drop-in
snippets into these .d/ directories can be placed in any
directory systemd looks for units in, and the usual
overriding semantics between /usr/lib, /etc and /run apply
for them too.
In this particular case that would mean creating a directory
/etc/systemd/system/tmp.mount.d/, then placing a .conf file in there
setting your custom options.
That all said, using /etc/fstab is perfectly fine if you need to tweak
the /tmp tmpfs settings.
An entry from /etc/fstab will override any existing tmp.mount unit.
