These checks were added when we required a specific version of containerd
and runc (different versions were known to be incompatible). I don't think
we had a similar requirement for tini, so this check was redundant. Let's
remove the check altogether.

Welcome to the v1.5.0 release of containerd!
The sixth major release of containerd includes many stability improvements
and code organization changes to make contribution easier and make future
features cleaner to develop. This includes bringing CRI development into the
main containerd repository and switching to Go modules. This release also
brings support for the Node Resource Interface (NRI).
Highlights
--------------------------------------------------------------------------------
*Project Organization*
- Merge containerd/cri codebase into containerd/containerd
- Move to Go modules
- Remove selinux build tag
- Add json log format output option for daemon log
*Snapshots*
- Add configurable overlayfs path
- Separate overlay implementation from plugin
- Native snapshotter configuration and plugin separation
- Devmapper snapshotter configuration and plugin separation
- AUFS snapshotter configuration and plugin separation
- ZFS snapshotter configuration and plugin separation
- Pass custom snapshot labels when creating snapshot
- Add platform check for snapshotter support when unpacking
- Handle loopback mounts
- Support userxattr mount option for overlay in user namespace
- ZFS snapshotter implementation of usage
*Distribution*
- Improve registry response errors
- Improve image pull performance over HTTP 1.1
- Registry configuration package
- Add support for layers compressed with zstd
- Allow arm64 to fallback to arm (v8, v7, v6, v5)
*Runtime*
- Add annotations to containerd task update API
- Add logging binary support when terminal is true
- Runtime support on FreeBSD
*Windows*
- Implement windowsDiff.Compare to allow outputting OCI images
- Optimize WCOW snapshotter to commit writable layers as read-only parent layers
- Optimize LCOW snapshotter use of scratch layers
*CRI*
- Add NRI injection points cri#1552
- Add support for registry host directory configuration
- Update privileged containers to use current capabilities instead of known capabilities
- Add pod annotations to CNI call
- Enable ocicrypt by default
- Support PID NamespaceMode_TARGET
Impactful Client Updates
--------------------------------------------------------------------------------
This release has changes which may affect projects which import containerd.
*Switch to Go modules*
containerd and all containerd sub-repositories are now using Go modules. This
should help make importing easier for handling transitive dependencies. As of
this release, containerd still does not guarantee client library compatibility
for 1.x versions, although best effort is made to minimize impact from changes
to exported Go packages.
*CRI plugin moved to main repository*
With the CRI plugin moving into the main repository, imports under github.com/containerd/cri/
can now be found github.com/containerd/containerd/pkg/cri/.
There are no changes required for end users of CRI.
*Library changes*
oci
The WithAllCapabilities has been removed and replaced with WithAllCurrentCapabilities
and WithAllKnownCapabilities. WithAllKnownCapabilities has similar
functionality to the previous WithAllCapabilities with added support for newer
capabilities. WithAllCurrentCapabilities can be used to give privileged
containers the same set of permissions as the calling process, preventing errors
when privileged containers attempt to get more permissions than given to the
caller.
*Configuration changes*
New registry.config_path for CRI plugin
registry.config_path specifies a directory to look for registry hosts
configuration. When resolving an image name during pull operations, the CRI
plugin will look in the <registry.config_path>/<image hostname>/ directory
for host configuration. An optional hosts.toml file in that directory may be
used to configure which hosts will be used for the pull operation as well
host-specific configurations. Updates under that directory do not require
restarting the containerd daemon.
Enable registry.config_path in the containerd configuration file.
[plugins."io.containerd.grpc.v1.cri".registry]
config_path = "/etc/containerd/certs.d"
Configure registry hosts, such as /etc/containerd/certs.d/docker.io/hosts.toml
for any image under the docker.io namespace (any image on Docker Hub).
server = "https://registry-1.docker.io"
[host."https://public-mirror.example.com"]
capabilities = ["pull"]
[host."https://docker-mirror.internal"]
capabilities = ["pull", "resolve"]
ca = "docker-mirror.crt"
If no hosts.toml configuration exists in the host directory, it will fallback
to check certificate files based on Docker's certificate file
pattern (".crt" files for CA certificates and ".cert"/".key" files for client
certificates).
*Deprecation of registry.mirrors and registry.configs in CRI plugin*
Mirroring and TLS can now be configured using the new registry.config_path
option. Existing configurations may be migrated to new host directory
configuration. These fields are only deprecated with no planned removal,
however, these configurations cannot be used while registry.config_path is
defined.
*Version 1 schema is deprecated*
Version 2 of the containerd configuration toml is recommended format and the
default. Starting this version, a deprecation warning will be logged when
version 1 is used.
To check version, see the version value in the containerd toml configuration.
version=2
FreeBSD Runtime Support (Experimental)
--------------------------------------------------------------------------------
This release includes changes that allow containerd to run on FreeBSD with a
compatible runtime, such as runj. This
support should be considered experimental and currently there are no official
binary releases for FreeBSD. The runtimes used by containerd are maintained
separately and have their own stability guarantees. The containerd project
strives to be compatible with any runtime which aims to implement containerd's
shim API and OCI runtime specification.

The flag ForceStopAsyncSend was added to fluent logger lib in v1.5.0 (at
this time named AsyncStop) to tell fluentd to abort sending logs
asynchronously as soon as possible, when its Close() method is called.
However this flag was broken because of the way the lib was handling it
(basically, the lib could be stucked in retry-connect loop without
checking this flag).
Since fluent logger lib v1.7.0, calling Close() (when ForceStopAsyncSend
is true) will really stop all ongoing send/connect procedure,
wherever it's stucked.

Commit dae652e2e5 added support for non-privileged
containers to use ICMP_PROTO (used for `ping`). This option cannot be set for
containers that have user-namespaces enabled.
However, the detection looks to be incorrect; HostConfig.UsernsMode was added
in 6993e891d1 / ee2183881b,
and the property only has meaning if the daemon is running with user namespaces
enabled. In other situations, the property has no meaning.
As a result of the above, the sysctl would only be set for containers running
with UsernsMode=host on a daemon running with user-namespaces enabled.
This patch adds a check if the daemon has user-namespaces enabled (RemappedRoot
having a non-empty value), or if the daemon is running inside a user namespace
(e.g. rootless mode) to fix the detection.
