Comment 3 for bug 1026622

I think this is unlikely to be a bug in either rpcbind or network-manager, but a bug in how your script is configuring things. It's normal for network-manager to comment out dhcp-only interfaces in /etc/network/interfaces, and for these network devices to be managed by network-manager; and rpcbind should in no way interfere with NM bringing up interfaces. This all works out of the box here for me and has for several releases.
