Hello,

if not mistaken,  sysfs  creates the '/sys/class/gpio' directory structure and the interface to the actual pins, right?

On an older centos version (7.1.1503), it is there  however on 7.8.2003 it's not.

Am I missing something?

The gpio handling was changed several kernels ago, IIRC you need you use libgpio now. I think I built it some time ago and put it here https://people.centos.org/pgreco/libgpiod/, let me know if it helps.
