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
