Public bug reported:

NOTE: this was originally reported in cpc-rax bug 1621968.  Re-reporting
here for tracking purposes as requested.  Please see that issue for log
files and more details.

In recent versions of cloud-init[1], we've found that when we attach a
configdrive to a cloud server cloud-init crashes before it has a chance
to complete its tasks - most critically, generating the SSH keys.

The root of this issue seems to be that cloud-init wants to parse the
included network config on the configdrive.. Our network config uses a
"null" vif type, which causes cloud-init to bomb out with an error like
this:

Sep 09 14:48:40 shtest2 cloud-init[2910]: ValueError: Unknown
network_data link type: None

[1]# dpkg -s cloud-init | grep ^Version
Version: 0.7.7~bzr1256-0ubuntu1~16.04.1
