* Replace "snap download" with tool that uses snap store's coherence feature
This is important for parallel image builds to ensure all pre-seeded snaps
have the same versions across image variants.
* Inject a proxy into the build providing a snapshot view of the package repo.
When the REPO_SNAPSHOT_STAMP variable is set, the auto/build script will attempt
to launch a transparent HTTP proxy on port 8080, and insert an iptables rule to
redirect all outgoing HTTP requests to this proxy.
The proxy, contained in the `magic-proxy` Python script, examines each request
and silently overrides those pointing to InRelease files or files that are
listed in InRelease files. It will instead provide the contents of the requested
file as it was at REPO_SNAPSHOT_STAMP, by downloading the corresponding asset
"by hash".
* Use series files with dependency handling to generate hook symlinks dynamically
This patch currently only applies to the "ubuntu-cpc" project.
More and more logic has been going into the hook scripts to decide
under which conditions they should run or not. As we are moving
to parallelized builds of image sets, this will get even more
complicated. Base hooks will have to know which image sets they
belong to and modification of the dependency chain between scripts
will become more complicated and prone to errors, as the number of
image sets grows.
This patch introduces explicit ordering and dependency handling for
scripts through the use of `series` files and an explicit syntax
for dependency specification.
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.
Kernels which are able to boot without initramfs now dropped dependency
on initramfs-tools thus initramfs-tools can be removed from the image
instead of having to divert it to avoid initramfs generation.
- Usually, netplan's systemd-generator enables systemd-networkd and
systemd-networkd-wait-online on boot. But netplan configuration is not
yet generated at that point by cloud-init. Cloud-init generates in the
network-pre.target and expects the network.target /
network-online.target to work. These are already part of the ongoing
systemd transaction, thus cannot be injected into the boot-sequency by
cloud-init local mode. Therefore make sure cloud images include
networkd in the initial boot transaction.
- src:systemd will shortly not enable networkd unconditionally by
default.
* Drop ifupdown e-n-i configuration files, no longer used.
