Remaining issues with reconciliation
--------------------------------------------
Note that both before, and after this change, the command sometimes terminates
early, and does not wait for the service to reconcile; this is most apparent
when rolling back is scaling up (so more tasks are deployed);

service rolled back: rollback completed

commit c2626a8270 replaced the use of
github.com/docker/docker/pkg/homedir with Golang's os.UserHomeDir().
This change was partially reverted in 7a279af43d
to account for situations where `$HOME` is not set.
In situations where no configuration file is present in `~/.config/`, the CLI
falls back to looking for the (deprecated) `~/.dockercfg` configuration file,
which was still using `os.UserHomeDir()`, which produces an error/warning if
`$HOME` is not set.
This patch introduces a helper function and a global variable to get the user's
home-directory. The global variable is used to prevent repeatedly looking up
the user's information (which, depending on the setup can be a costly operation).

Commit f32731f902 fixed a potential panic
when an error was returned while trying to get existing credentials.
However, other code paths currently use the result of `GetDefaultAuthConfig()`
even in an error condition; this resulted in a panic, because a `nil` was
returned.

The created time of the containerd is initialized with nanoseconds,
it seems to be a mistake.
In other places of the code, this field is initialized with seconds:
$ grep -rh 'time\.Now()\.Unix()' | grep Created
Created: time.Now().Unix(),
Created: time.Now().Unix(),
return []image.HistoryResponseItem{{ID: img, Created: time.Now().Unix()}}, nil
We can also see the the formatter assumes it to be seconds:
cli/command/formatter/container.go
----
func (c *ContainerContext) CreatedAt() string {
return time.Unix(c.c.Created, 0).String()
}
Interestingly, initializing the field with nanoseconds seems to work,
except on mips architecture, where it causes some kind of overflow.

Distributions uses generate-man.sh to create man pages, however it only
assumes a container environment and attempts to build binaries towards
`/go` which might be an illegal path in `fakeroot`.
This patch ensures we only build `md2man` from the vendored sources if
the command is not present. This allows distributions to supply thier
packaged `md2man`.

Docker Engine v20.10 and up includes optimizations to verify if images in the
local image cache need updating before pulling, preventing the Docker Engine
from making unnecessary API requests. These optimizations require the container
image registry to conform to the Open Container Initiative Distribution Specification
(https://github.com/opencontainers/distribution-spec).
While most registries conform to the specification, we encountered some registries
to be non-compliant, resulting in `docker pull` to fail.
As a temporary solution, Docker Engine v20.10 includes a fallback mechanism to
allow `docker pull` to be functional when using a non-compliant registry. A
warning message is printed in this situation:
WARNING Failed to pull manifest by the resolved digest. This registry does not
appear to conform to the distribution registry specification; falling back to
pull by tag. This fallback is DEPRECATED, and will be removed in a future
release.
The fallback is added to allow users to either migrate their images to a compliant
registry, or for these registries to become compliant.
Note that this fallback only addresses failures on `docker pull`. Other commands,
such as `docker stack deploy`, or pulling images with `containerd` will continue
to fail.
Given that other functionality is still broken with these registries, we consider
this fallback a _temporary_ solution, and will remove the fallback in an upcoming
major release.
