This is what's in the script.

/home/parazyd/arm-sdk/

You might like to know that parazyd builds all of the arm stuff.

Surely this is a typo: /home/paralyzd/arm-sdk....

Geesh . . . I was just trying to help but that will likely be the last time. 

Just something to think about . . . very few things in this world are under our 'control'.  The control that we do have  is in the mind that perceives the uncontrollable.   There is truth in what you say but it has taken you down quite a rabbit hole.  Please stop trying to pull us in with you.  Wasted bits and bytes . . .

Here's a suggestion . . . do you know that devuan has no-systemd version of tails?

That might suit you perfectly.

Ever consider a walk in the woods or on the beach?

Congrats!  Are you a scruffy old graybeard?  You probably look too intelligent to be chosen.

Yes to both of these statements.  Forcing non-free is as offensive as limiting its availability.  Crusaders are entitled to their opinion but  it is just that.  The choice to use or not use non-free is the USER's.  ATM, that part of the installer is being carefully scrutinized, tested and updated to ensure consistency.  As to pressing the wrong key . . . who of us hasn't done that a time or two.  You take your lumps and move on.  But it's PEBKAC, not the installer's fault.

Self-verification should put your mind at ease.  In the meantime, please just take a deep breath and try not to let your imagination take you down paths that are stressful for you and waste all our time and energy.

Have you tried the ascii beta which is forked from Debian Stretch?

I remember hearing about issues with rufus.  Search this forum and quite a few posts reference it.  Might be something in there to help you sort things

Yes.  We know them.  I will pass along your message.

Maybe a compositing issue?
