Noam Angel f1369a1add Set manifest permissions in the image This is a follow-on to `57ef187632`. There's two things going on here; DIB_MANIFEST_IMAGE_DIR is outside the chroot on the build host. We copy the files here for posterity, I guess. MANIFEST_IMAGE_PATH is inside the chroot and are the files we want to ensure are locked to root. The prior change modified the permissions on DIB_MANIFEST_IMAGE_DIR. So the first time you build, it works -- then the second time, assuming you're using the same output filename, it hits the root-owned manifest directories and causes a build failure. I have built with this and checked that the manifest files in the image are locked to root: $ virt-ls -a ./test.qcow2 -l /etc/dib-manifests total 32 drwxr-xr-x 2 0 0 4096 May 24 03:39 . drwxr-xr-x 53 0 0 4096 May 24 03:39 .. -rw------- 1 0 0 15236 May 24 03:39 dib-manifest-dpkg-test -rw------- 1 0 0 35 May 24 03:39 dib_arguments -rw------- 1 0 0 137 May 24 03:39 dib_environment Related-Bug: #1671842 Change-Id: I08319d0b5fcc461d40fe0be8427dcf0e37ad21e6		2017-05-24 15:20:55 +10:00

=========
manifests
=========

An framework for saving manifest information generated during the
build for later inspection.  Manifests are kept in the final image and
also copied to the build area post-image creation.

Elements that wish to save any form of manifest should depend on this
element and can save their data to into the ``DIB_MANIFEST_IMAGE_DIR`` (
which defaults to ``/etc/dib-manifests``).  Note this is created in
``extra-data.d`` rather than ``pre-install.d`` to allow the
``source-repositories`` element to make use of it

The manifests are copied to ``DIB_MANIFEST_SAVE_DIR``, which defaults
to ``${IMAGE_NAME}.d/``, resulting in the manifests being available as
``${IMAGE_NAME}.d/dib-manifests`` by default after the build.

Extra status
------------

This element will also add the files ``dib_environment`` and
``dib_arguments`` to the manifest recording the ``diskimage-builder``
specific environment (``DIB_*`` variables) and command-line arguments
respectively.
