  2. sys-process/tini: Apply Flatcar patches

  3. app-emulation/docker-cli: Import from Gentoo 

    Docker upstream split the cli component into a separate repo, so there is
a separate ebuild that builds the docker utility. This is a prerequisite
of the update of docker to 20.10.

This is an import from portage commit 69d01a4273a556b1205a7a575cb3811ab7e2443d.

  4. app-emulation/docker-cli: Apply Flatcar patches 

    We use coreos-go* eclass so that we can override several environment
variables and build with the same go version as docker upstream. These
changes are modeled after what was previously done in app-emulation/docker,
the cli ebuild has only been split out since v20.10.

  5. app-emulation/docker-proxy: Freeze version 0.8.0_p20180709 

    This is the version used by docker-19.03. We will be updating the live
ebuild to build docker 20.10 dependencies.

  6. app-emulation/docker-proxy: Update to 0.8.0_p20210525 

    This is the version needed by docker 20.10.7. ROADMAP.md doesn't exist so it
has been removed from src_install.

  8. app-emulation/docker: Apply Flatcar patches 

    The patches do the following:

* install flatcar specific wrappers and systemd config
* force some USE flags to default on
* allow injecting CFLAGS/LDFLAGS so that torcx can work
* force building with go1.13 (like upstream does) - this won't be
  necessary next time because docker master already uses go1.16

  9. app-torcx/docker: Add a Docker 20.10 torcx image 

    Compared to previous torcx images the docker-cli package is a separate
package, following upstream Docker repo layout changes.

  10. coreos-base/flatcar-eks: update supported kubernetes versions for cgr… 

    …oupv2

We are switching flatcar to cgroupv2 which is support by docker 20.10 and
kubernetes 1.19. This requires setting the systemd cgroup driver in the kubelet
config.

Due to the unified cgroup hierarchy, kubernetes <1.19 will not work so
remove all older versions.

  11. .github: Adapt docker-release-main action to Docker 20 

    The upstream docker repository location has changed to docker/docker.
Additionally, the cli component has been split out which which requires
fetching two hashes and updating two ebuilds. We also took the chance to
align the ebuild with gentoo's, which means there are is no more live ebuild
and no symlink.

  13. sys-apps/systemd: Switch to unified cgroup hierarchy 

    Now that Docker has been updated to 20.10, we can use cgroupv2 so have
systemd mount the unified cgroup hierarchy by default. Other ways of
achieving the same would have been to pass 'systemd.unified_cgroup_hierarchy=1'
on the kernel cmdline, but this way the change propagates nicely to all
OEM consumers.

  16. app-emulation/containerd: add config file for use during migration 

    The SystemdCgroup=true setting is incompatible with kubelet
cgroupDriver: cgroupfs. So to prevent kube clusters from failing, we
will be freezing a nodes config.toml during an update. For that purpose,
we install a second configuration file that can then be selected using a
systemd drop-in unit.
