Status changed to 'Confirmed' because the bug affects multiple users.

[Faye Salwin (faye-salwin)]

The interface was set to renameX during installation, I suspect because dhcp was triggered before udev had settled.
This named my interface renameX in /etc/network/interfaces, which meant that network-interface.conf was triggering when it saw the renameX interface.

Changing the interface name in /etc/network/interfaces to p1p2, the next reboot brought the interface back with the p1p2 name.

Faye, I have p4p2 in my interfaces file and it still gets renamed to rename3.

this are two dmesg outputs when I only restarted my server, no files changed or anything.
