We never support module unloading. It's almost always wrong to do that.

Module unloading is a 'development tool', or to *locally* work around
broken drivers, we will not support that with any tools and advertise
that, or make it easy to do so. It steals the focus from the kernel
bugs, which is just bad. Module unloading is usually only fixing the
symptoms, not the cause, which is an approach systemd refuses to
support.

If you need to unload modules, file bugs against the kernel please, so
that this gets fixed. Modules need to be able to stay loaded all the
time; just the same way they could be compiled-in in the first place.

Systemd can force-load modules with 'man modules-load.d'.
