@ddstreet tested with the latest version of ifupdown and vlan from your PPA with my 4 testscenario's and can confirm it works as expected. Interfaces come up correctly both when doing an "ifup -a" and during boot.
One small thing I've noticed is a variation in the number of "Set name- type for VLAN subsystem. Should be visible in /proc/net/vlan/config" messages in the ifup output depending on the different scenario, even though the number of vlans is the same in all 4 tests. With 2 vlans, the 2 scenario's with bonding generate 1 message, the ones without bonding generate 4. It doesn't hurt, just something I noticed. Please check the attached log for more details on my 4 tests. ** Attachment added: "Test output for 4 different scenario's" https://bugs.launchpad.net/ubuntu/+source/vlan/+bug/1701023/+attachment/5124886/+files/vlan-tests.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1701023 Title: (on trusty) version 1.9-3ubuntu10.4 regression blocking boot completion To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1701023/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
