Having better docs for this would have saved me a few tense hours with a remote system without console access. The official Ubuntu docs are still wrong and various online helps points people to a confusing array of docs from other distros.
Long story short: a brand new Ubuntu 14.04 system seems to have biosdevname installed, which gives ethernet devices names like /dev/p4p1. An old Ubuntu 12.04 system upgraded to 14.04 does not get biosdevname, and uses old names like /dev/eth0. If a user (like me) installs biosdevname manually then on next reboot the devices will be given the new names, breaking the network configuration unless the user reconfigures /etc/network/ interfaces.
