Before oneiric ifupdown used ifconfig to set the network interface and with oneiric iproute2 is used. iproute2 assigns new IPs directly to the interface, e.g. eth0, if you like to have a virtual interface eth0:0, you have to add a label explicitly.
ifconfig eth0:0 x.x.x.x up vs. ip addr add x.x.x.x/x dev eth0 label eth0:0 I assume ifupdown misses to set the label with iproute2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/876829 Title: Oneiric's ifupdown breaks ip aliases To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/876829/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
