integration test: replace curtin test ppa with cloud-init test ppa.
Cloud-init integration tests should not depend on a curtin test ppa.
We already had a cloud-init test ppa for explicitly this purpose.
Just use it instead.
EC2: Fix bug using fallback_nic and metadata when restoring from cache.
If user upgraded to new cloud-init and attempted to run 'cloud-init init'
without rebooting, cloud-init restores the datasource object from pickle.
The older version pickled datasource object had no value for
_network_config or fallback_nic. This caused the Ec2 datasource to attempt
to reconfigure networking with a None fallback_nic. The pickled object
also cached an older version of ec2 metadata which didn't contain network
information.
This branch does two things:
- Add a fallback_interface property to DatasourceEC2 to support reading the
old .fallback_nic attribute if it was set. New versions will
call net.find_fallback_nic() if there has not been one found.
- Re-crawl metadata if we are on Ec2 and don't have a 'network' key in
metadata
EC2: Kill dhclient process used in sandbox dhclient.
dhclient runs, obtains a address and then backgrounds itself.
cloud-init did not take care to kill it after it was done with it.
After it has run and created the leases, we can kill it.
centos: Provide the failed #include url in error messages
On python 2.7 and earlier (CentOS 6 & 7), UrlErrors raised by requests do
not report the url which failed. In such cases, append the url if not
present in the error message.
rh_subscription: Perform null checks for enabled and disabled repos.
The rh_subscription module doesn't perform null checks when attempting to
iterate on the enabled and disable repos arrays. When only one is
specified, cloud-init fails to run.
Improve warning message when a template is not found.
At present the location for the template file look up upon failure
includes the template file itself. However based on the wording of the
message it should only contain the template directory issue
