The livecd.ubuntu-cpc.ext4 that is present in each build (plus kernel
and initrd) are not renamed from /build/binary/boot/filsystem.ext4
and friends until after the binary hooks are run, so this patch moves
from trying to perform this cleanup in a binary hook. Now the cleanup
will be run at the end of live-build/binary for the ubuntu-cpc project.
In parallel builds where a list of image targets are provided the build
may produce binaries that are not part of the named set of targets but
are created by series dependencies. These implicitly created binaries
may be generated by multiple builds but are unused as our convention for
the ubuntu-cpc project is to only consume binaries from the explicitly
named image targets; this avoid overwriting the same object by multiple
parallel builds.
This patch adds support for a 'provides' keyword for series files. It can
be specified multiple times per series file. The field is used by the
make-hooks script to generate a list of output files created explicitly by
the named image targets. The list is saved to the "explicit_provides"
file in the hooks output directory. In the case of the "all" target
this list would be empty. This list is consumed by the "final.binary"
hook file.
This patch adds support for optional final.binary hooks in hooks.d/base
and/or hooks.d/extra. These final.binary hooks are always included as
the last hook(s) if either exist with the hook in "extra" running last.
The base/final.binary hook includes logic to parse the "explicit_provides"
file generated by the make-hooks script and remove any binary output not
explicitly specified.
Some series files named unnecessary dependencies, specifically
disk-image, to keep output of implicit artifacts consistent between
parallel builds. These unnecessary dependencies are removed in this
patch.
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 overwrite this artifact.
This patch ensures that all targets will produce consistent base output.
An upcoming addition of the disk-image target to several series files will
required some explanation. Without comment support in series files that
is not possible. This patch adds support for comments in series files.
* ubuntu-cpc: Generate the root image contents once, and use it for both the
-root.tar.xz and the .squashfs.
* ubuntu-cpc: Generate -root.tar.xz with --xattrs.
don't want installed by default. Some are tools that aren't needed for
non-interactive use; some are libraries whose reverse-dependencies
will have already been removed; and one, open-vm-tools, should only be
included in images that are targeted to VMWare (which is not the case
for any of the current minimal images), rather than being included
directly in the cloud-image seed.
