Code Issues Proposed changes

Retire Packaging Deb project repos

Browse Source 
This commit is part of a series to retire the Packaging Deb
project. Step 2 is to remove all content from the project
repos, replacing it with a README notification where to find
ongoing work, and how to recover the repo if needed at some
future point (as in
https://docs.openstack.org/infra/manual/drivers.html#retiring-a-project).

institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses

of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

os-refresh-config
=================
`os-refresh-config` uses `dib-run-parts` to run scripts in a
pre-defined set of directories::
/opt/stack/os-config-refresh/pre-configure.d
/opt/stack/os-config-refresh/configure.d
/opt/stack/os-config-refresh/post-configure.d
/opt/stack/os-config-refresh/migration.d
/opt/stack/os-config-refresh/error.d
`/opt/stack/os-config-refresh` is the default base directory. You can
set `OS_REFRESH_CONFIG_BASE_DIR` environment variable to override the
default one.
Its intended purpose is to separate scripts execution into 4 phases:
1. Quiesce(pre-configure.d),
2. Configure(configure.d),
3. Activate(post-configure.d).
4. Migrate(migration.d),
It runs through all the phases above to ensure configuration is applied
and enabled on a machine. It will run the scripts in error.d and then
exit with a non-zero exit status if any phase has a problem. The scripts
in each phase should not depend on each other having worked properly.
Note: Earlier versions of os-refresh-config ran migration before
post-configure. This was an oversight in the initial design, as
migrations are intended to be online migrations after the host is
fully configured.
For things which must happen while the service is quiesced, that should
be done in the post-configure scripts which control the service state.
