>Description:

	Despite the proper permissions on the /dev/tun? files, the tun-devices
	can only be opened by root. It seems, the tun-driver checks for this,
	without an obvious good reason...
	
	In addition, I'd like to be able to delegate an interface configuration
	to a non-root user, who is able to write to the device...

>How-To-Repeat:

	mi@chubby:~ (84) ls -l /dev/tun3
	crw-rw----  1 mi  dialer   52,   3 Jun  1 11:00 /dev/tun3
	mi@chubby:~ (85) groups
	mi dialer operator wheel
	mi@chubby:~ (86) cat /dev/tun3
	cat: /dev/tun3: Operation not permitted
	mi@chubby:~ (87) whoami
	mi
