[Bug 1827426] Re: ubuntu-cpc: parallel build targets produce different root FS output

[Steve Langasek]

Hello Robert, or anyone else affected,

Accepted livecd-rootfs into disco-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/livecd-
rootfs/2.578.4 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-disco to verification-done-disco. If it does not fix
the bug for you, please add a comment stating that, and change the tag
to verification-failed-disco. In either case, without details of your
testing we will not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: livecd-rootfs (Ubuntu Disco)
       Status: New => Fix Committed

** Tags added: verification-needed verification-needed-disco

Title:
  ubuntu-cpc: parallel build targets produce different root FS output

Status in livecd-rootfs package in Ubuntu:
  New
Status in livecd-rootfs source package in Disco:
  Fix Committed

Bug description:
  [Impact]

  The following targets have livecd.ubuntu-cpc.manifest (and
  livecd.ubuntu-cpc.ext4) which differ in some way from the 'all'
  target. They are all missing grub-efi and other modifications:

  root-dir
  squashfs
  tarball

  These targets do not depend on the 'disk-image' target. This means that
  the ext4 produced will lack the uefi modifications (and any from the
  disk-image target binary hooks).

  Since the ext4 file is common to all builds there is a chance that a
  parallel build from one of these targets could mistakenly be used.

  [Test Case]

  A build of each of the above mentioned image targets must produce a
  root filesystem that is the same as the 'disk-image' or 'all' target.

  [Regression Potential]

  None.  Image targets are not yet in use in production for the ubuntu-cpc project and the changes do not affect builds without specification of an
  image target.

  [Other Info]

  This is blocking backporting of image parallelization to the rest of our
  supported releases (and consumption of the feature overall) making it
  a high priority for us to see these in place.
