At least for me, under the circumstances described below, the presence of an empty file named "wizard-has-run" in .config/ubuntu-system-settings/ does NOT prevent the tutorial from starting.
I installed Ubuntu Next fresh from the 08-Apr-2015 daily build from http://cdimage.ubuntu.com/ubuntu-desktop-next/daily-live/current/ Upon first boot into the freshly installed system, I got the tutorial. Upon rebooting using the installation disk, and selecting the "try ubuntu" option, I can find that that an empty file named "wizard-has-run" is already present in .config/ubuntu-system-settings/ on the system disk. But even though the empty file named "wizard-has-run" is already present on the system disk, upon booting again into the freshly installed system, I still get the tutorial.
Perhaps the situation would be different if I had added the empty file named "wizard-has-run" immediately after installation of, but before first boot into, the system. I don't know. I haven't tried that. But again, I can confirm that, at least for me, under the circumstances described above, the presence of an empty file named "wizard-has-run" in .config/ubuntu-system-settings/ does NOT prevent the tutorial from starting.
