yes, it seems to work. 
i’ve retested installation on centos 6.7 minimal (both dhcp and fixed ip)
back to rc1 testing: i think we have tested all the different installation type, so we can start testing the packages, and i’ll ask again:
apart nethserver-vpn and nethserver-monitoring, does anyone have tested others modules on 6.7rc1? if yes please report here, it could save a lot of time to other testers. tnx
