Mainly revert 869d44c30e 

Fixing #304 doesn't look trivial

The service module needs to know the arguments right away.

The arguments haven't been parsed yet. And if we do, we will prevent
further arguments to be added to the set. Including the ones added
by the service module itself.

So, we have quite of a circular dependency here.

If someone with some Go knowledge can fix that, that would be amazing.
But it's probably never going to happen.

Meanwhile, we can try to save the current directory and document
that we have to be in that directory when running the install command.

Which is not going to work on Windows, so this is a big fucking mess
