Default Displaylink on Fedora 22

I got the new DisplayLink driver working for Fedora 22 with Kernel 4.1.3. Had to make a few changes to the install script. Here is the modified script.

It's working perfectly, but I have to re-run the install script to get the displaylink service running after every boot. I tried to use Fedora's built-in systemcl command to get it to run the service on startup, but it fails:

Code:
$ sudo systemctl enable displaylink.service                    
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).
Anyone have any ideas?

I can confirm that this works on Fedora 22 with the 4.1.4 kernel. My system uses efi so I had to sign the kernel mod. There are a few guides on how to do it for Virtualbox, the same principles apply with this.

I created my own rpm for Fedora 22, and added a udev rule so that the service is started when the device is plugged in, and stopped when plugged out. Also keeps dkms so that kernel updates won't break it.
