Gary Dotzler 17a3a87f6e procd: assign conventional /dev/net/tun permissions
Set /dev/net/tun to mode 0666, matching the TUN/TAP permissions
documented by docs.kernel.org[1] and the default udev policy used by
other Linux systems[2].

This avoids forcing otherwise unprivileged processes to retain elevated
privileges solely to open the device node.

Interface creation and attachment remain subject to the kernel's usual
capability and ownership checks.
