How do everyone, after a break from the project I am back to working on the render farm and I was wondering what Linux distro would be best for the render nodes.
it depends on how you want to use your render node.
For a system with a GUI and a DE, I recommend using a (small) Ubuntu LTS based distro like Linux Mint XFCE If you want to have a headless render server, I recommend Debian 10 with Docker on top, this way you minimize the overhead of the system itself.
If you need help in setting it up, feel free to ask me. ;)
