If I restart the interfaces manually, by doing "ifdown xiondata; ifup -a" the MTU settings seem to be applied correctly every time. root@controller-node13:~# apt policy ifupdown ifupdown: Installed: 0.8.10ubuntu1 Candidate: 0.8.10ubuntu1 Version table: *** 0.8.10ubuntu1 500 500 http://eu.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: ifupdown 0.8.10ubuntu1 ProcVersionSignature: Ubuntu 4.4.0-38.57-generic 4.4.19 Uname: Linux 4.4.0-38-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 Date: Tue Oct 4 09:44:40 2016 ProcEnviron: LANGUAGE=en_US: TERM=screen PATH=(custom, no user) LANG=en_US.utf8 SHELL=/bin/bash SourcePackage: ifupdown UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1630191/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
