It’s an extremely bizarre suggestion given your request. I do want to defend the game (though not the suggestion) a little though.
It initially presents as you say, but offers you opportunities to fight back in your capacity as border control. Letting in the right people can help the resistance and incite a coup, or enable you and your families escape from the country. It isn’t just Be A Good Tankie Simulator 2013, though you can play it that way too.
Even if you are confident in your Linux skills this isn’t a bad idea. I’ve seen too many OS installers put things on drives other than the one you choose to risk it at this point.
