Is it possible to have a full unix system running inside of UE4

I was just looking to see if It was possible to have a full or mostly full version of a UNIX operation system run inside of a project. I was thinking of something similar to GTFO but a full system instead of a few commands. Does anyone know if it is possible to do something like this? Thank you.

Not inside of a engine, UE4 is not very unix-like it fact it does not use C++ standard library. But you could run OS else where and just hook up io to the engine
