No GPIO group on Armbian?

[wollik]

Hi Members,
I'm setting and reading the GPIO PINs for different BPI's frequently only by bash by maintaining the /sys/class/gpio/xxx values.
The only problem is that all these files belong to root :root and I have to use the sudo command in my scripts.
I've read about putting a non root user to the gpio group will fix that.
But on Armbian there is no "gpio" group ;(
That seems the reason why the directory /sys/class/gpio is not prepared as root:gpio

Please has someone an idea when this will be implemented?

Regards
wollik

When you will add this with a PR here:
https://github.com/armbian/build/blob/main/packages/bsp/common/usr/lib/armbian/armbian-firstlogin#L601

and group before that.

@cOrnelius
YES I know how to maintain the current system manualy, but with the next release I' l have to do it again.

@Igor,
your PR modification looks like the right solution adding the missing group T H A N K S!
P L E A S E  can you also point me where I will find the right spot where I can define the right owner for the some specified directories like the: /sys/class/gpio ? Is there a list for mapping the right owner to a  directory? that can be modified?

Regards

Wolfgang
