Current situation

As Flatcar is being included in more edge deployments (amd64 and arm64), there are integrations with devices needed (sensors, cameras, etc.), which is not included

Impact
blocks certain edge use-cases

Ideal future situation
GPIO is present so folks can continue doing cool stuff on Flatcar

Implementation options
CONFIG_GPIO_SYSFS so that /sys/class/gpio/... is present, and /dev/gpiomem is present
