Comment 1 for bug 948559

contrib/network requires things like /etc/sysconfig/ (a RHism) and isn't installed; vlan_test{,-2}.pl are test scripts and are not installed.

For the rest, the documentation currently advises using the 'vlan-raw-device' entry in /etc/network/interfaces, although I agree that we should support the biosdevname interface names out of the box anyway.
