by allowing openvpn --mktun to be used with --user and --group to set the UID/GID of the tun device node. Also added --iproute option to allow an alternative command to be executed in place of the default iproute2 command (Alon Bar-Lev). git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@2639 e7ae566f-a301-0410-adde-c780ea21d3b5
