[Impact]
This update to curtin is required to support features of MAAS 1.9 that is being SRU'd to trusty and wily under bug 1509147. There are also numerous bug fixes that affect the code path used with older maas as well. See the changelog entry below for a full list.
Changes to wily and xenial much more bug fix only.
[Test Case]
The test case is really MAAS 1.9 functionality. The MAAS bug 1509147 should include methods for verifying this.
For curtin's part, curtin now contains fairly extensive continuous integration test on trunk.
Those results can be seen at https://server-team-jenkins.canonical.com/job/curtin-vmtest-venonat/ .
[Regression Potential]
The chance for regression here is most likely in using curtin with an older MAAS release.
[Other Info]
The version of curtin here is completely backwards compatible with previous versions of MAAS and previous versions of curtin. Specifically a user could take curtin update without MAAS 1.9 SRU to trusty and be fine.
There are dramatic changes to curtin between the version in 14.04 and what is being SRU'd. This will no doubt be alarming to a user. However, there has been extensive work on improving curtin's test suite both in actual install tests in a VM and in uniti tests.
== End SRU Template ==
In order to support MAAS sru of 1.9 into trusty, we need a newer version of curtin.
Below is the combined debian changelog.
* debian/new-upstream-snapshot, debian/README.source: add
new-upstream-snapshot and mention it in README.source
* debian/control: drop python from curtin-common Depends.
remove unnecessary Depends on util-linux as it is essential.
python3-curtin, python-curtin: drop unnecessary 'curl' from Depends.
python3-curtin, python-curtin: list oauthlib and yaml Depends
* debian/control: add bcache-tools to curtin Depends.
* New upstream snapshot.
