I want to use CentOS 8 for desktop / development (blender-python3.7, unity for linux (game engine)). Do not publish outside the LAN (WAN-> LAN port mapping is not performed on the router side) Almost the first time (I used it a little in a university circle about 5-10 years ago) To-do list
Update to the latest BIOS before installation (because RDRAND is dead Ryzen 3 ASRock X570 Pro4 (BIOS v1.0))
Partition (only one NVME m2 512GB) --MBR default -/ boot 1GB (If you have it, can you afford it? Now the kernel is about 100MB?
