The title says it all. Must /dev/random and /dev/urandom be created each boot, or are they static files that can be put in a tar?

I am trying to understand if I need to recreate these each time the operating system starts, or if once created they do not need to be created again.

And related question, once created, can these two devices be put into a tar and restored?
