we have to add our own rules file, which contains only one rules
so far, because udev 174 comes without a rule for mounting the
fusectl system.

Adding the rule to the fuse port isn't a senseful option, because
udev still has one rule for fuse.
Well, I bet we have to do similar things more often in the future,
because udev is going to be systemd centric.
