[Feature Request] mknod_and_own_dev and permissions to the group

mknod_and_own_dev

I’ve had some issues automating the deployment of Firecracker when creating the tap device. I had to grant permissions to the group in order to work. One question: why does only the user have permissions?

Best regards.

Hey, thank you for opening this issue. Could you explain more in detail why you need the group to be added in the permissions of the device? As only Firecracker accesses this node, the user should suffice.
