Website RT Kernel Instructions

[AlexanderKhazatsky]

Hello, just a heads up: our lab historically hasn't been able to successfully build the RT kernel through the procedure on the website. When we follow it, we consistently encounter build errors on the kernel.

Instead, we use the Polymetis prerequisites page from steps 1 to 2. Then we use this page from "Compiling the kernel" and onward. For some reason going this route avoids the issues we run into when exclusively following the Polymetis procedure, I don't know why.

Just figured I would bring this to your guy's attention :)

Just a comment, but this method also only works with Ubuntu 18.04. The 20.04 setup doesn't work for me even if I follow the above instructions.

Bump, could be nice to have setup instructions specify ubuntu 18 + the above instructions to keep people from getting confused :)
