Feature added by: Thiago Sayao (sayao) Feature #310004, revision 1 Title: use network manager by default instead of traditional method openSUSE-11.3: Unconfirmed Priority Requester: Important Requested by: Thiago Sayao (sayao) Description: Use network manager by default instead of traditional method. Network Manager integrates better with the desktop and seems easier to configure (for example, to configure a VPN). I'm not sure about the features the traditional method provides and Network Manager does not, so please, discuss.   -- openSUSE Feature: https://features.opensuse.org/310004
