tl;dr - a renamed dummy interface is not persisting across reboots on Cent6. I have a situation where I need to rename a dummy interface on my system. I have a total of 3 dummy interfaces: dummy0 dummy1 adummy0 I've been doing some puppet testing in a vbox VM to get this all sorted out to deploy to a group of boxes. Every time I reboot my VM, it comes up WITHOUT adummy0, but I notice there is now an unconfigured dummy2. I've tried everything from adding aliases to /etc/modprobe.d/dummyopts.conf to renaming the interface via "ip" (ip link set dummy2 name adummy0). This is all fine during use, even during a network restart. But as soon as I restart the VM, it comes back up broken. I for the life of me have been unable to figure out why. I could use some help in narrowing down why this won't persist across reboots. I can write a startup script to deal with it, but it doesn't seem like a good solution. Thanks, Frank
