basically it should detect your "first user" to add the extra sudoers confs, it should rely on /etc/elive-version "first-user:" entry if you don't have a single user dir in /home
but i improved the installer so that "generic sudo" confs are added for all the users (like brightness or elive-upgrader) too, so it should be fixed now 
the installer alredy copy these files, and creates new sudoers confs as explained before. It will not create sudoers confs for extra things like apt-get (thats only for the first-user one), but will (should) do for elive-upgrader tool (which uses apt but is not an user use of apt itself)
that's a wrongly created one, you can simply remove this file (the updated installer will remove it too)
ok there's 2 different features in the elive installer, which works very similar in fact:
- upgrade mode: it upgrades your elive install reciclating the users
- migration mode: it converts your other OS to elive
the process is almost the same thing, but the first one will ask you directly before to select partition where to install, the second one doesn't "scan + detect" it until you select the partition where to install and then it tells you "hey, there's another system already installed, you want to migrate it?"
a few ones are not allowed (pass will not work) and the tool should suggest you to not use them, like ' or " IIRC
im actually in colombia with GF, my return flight is on end of july 
you need an update package for make it working, not sure if included in 3.7.6 but should be in the next build
works for me, can you describe the problem? note that urxvt is a different terminal than terminology, right-click on it and if a gui menu appears, you are in terminology and not urxvt
depending of the machine resources, one of other is selected by default

mmh, can you describe the steps to reproduce this issue? and your actual resolution used
