[SRU] Release all touch overlay PPA changes to the main archives for livecd-rootfs

[Łukasz Zemczak]

[Impact]

For the ubuntu-touch initiative development we are using the stable-phone-overlay PPA. So far we also used the same PPA to host our livecd-rootfs changes for our xenial images but we finally decided to SRU all the changes and start using the archive instead. Without these changes SRUed we are forced to do a sync re-release of livecd-rootfs to the overlay PPA every time a new xenial-updates version is released, which slows us down and is completely pointless.
The list of changes that this SRU covers:

 * Temporarily change the 60-install-click.chroot script to pull in clicks for arm64 builds from a different location for ubuntu-touch. This is a workaround we use for our arm64-experimental builds where we need to use separately built arm64 clicks, as the store only hosts armhf binaries right now.
 * Add the new dhcpd user to touch hooks introduced by latest archive changes.
 * Remove the ubuntu-pd project logic. The ubuntu-pd project is no longer used since almost half a year now.
 * Synced ubuntu-touch-custom changes from the vivid branch to xenial. The ubuntu-touch-custom cdimage project is a project we use to build custom re-builds of ubuntu-touch. It has exactly the same configuration as the regular ubuntu-touch project but uses separate builders and a separate export place in cdimage.

[Test Case]

No particular test case. Without these changes, xenial touch builds would not work at all - all the touch builds so far used the very same livecd-rootfs changes as are now proposed for the SRU.

[Regression Potential]

No regression potential, the changes should not affect anything besides touch. And for touch, as already mentioned above, we are using these changes in production since the release of xenial.

[Other Info]

The change to pull in clicks for arm64 for a different location is not released in the development series as we do not intend to build arm64 images on yakkety. This would also require rebuilding arm64 yakkety-based clicks which is not in our current plans.

Version with the required changes has been pushed to xenial-updates, waiting in the unapproved queue.

Are these changes in yakkety yet?

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Łukasz Zemczak (sil2100)]

The exact same changes have been used to successfully build an image in xenial ubuntu-touch. Verification done.

The verification of the Stable Release Update for livecd-rootfs has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
