First, this has nothing to do with systemd. The service you found is only
used to trigger manual loading of modules that didn't get loaded
automatically – but that doesn't mean systemd is actually doing all the
loading.

That's initiated by kmod (e.g. using `modprobe cifs`) and done by the
kernel on its own, so "unknown symbol" in dmesg has nothing to do with
systemd. You're probably trying to load the wrong module version; compare
`modinfo cifs` with `uname -a`.

Second, both "fuse" and "cifs-utils" packages only contain the *userspace
tools* – the actual kernel modules are part of the kernel package itself,
as you can see from `dpkg -S <path_from_modinfo>`.
