"effect" still needed to be changed to "affect" in that blog post
Anyway, I have tested Option#1 of generating a non-customized DisposableVM-Template which works.
So, you can remove the "untested" tag from the wiki here:
Option #1: Use a non-customized DisposableVM-Template. (untested) This template will use a stock image based on whonix-ws and will not preserve any changes that are made to it.
Re: "Adding shortcuts to applications menus", which is also untested in Qubes 3.2, I have followed the steps up to this point:
Once the .desktop files have been created, they need to be added to your Applications menu. Use a text editor to edit the following file.
Note: There is NO xfce-applications.menu entry anywhere in the template. I have searched using find and ls to no avail. Using kwrite as above just creates a new (empty) file.
Surely Marek knows where this (.menu file) is stored for dispVM template in the Qubes architecture? After all, the entry for the original DispVM menu can be edited to replace Firefox with the Tor Browser entry instead via Alt F3 in dom0.
So where is it? Adding the additional .desktop entries should be simple enough. Maybe he can give us some pointers.
I have not attempted the menulibre option, as I don't want to bork my menu as per other people's recent experiences.
