This is only a temporary measure and once we fix fab, you will be able to install the bugfix via apt (and remove the above code from your conf script- or start again with a new TKLDev). This is far from ideal, but allows us to push forward with the v17.x release, whilst take the time to ensure a proper fix. Feedback encouraged
