Turns out that `-f` on a file that's in `.dockerignore` actually does work. No idea why it wasn't when I was doing this before, but oh well! 🤘

From the Bash manual's `set -e` description:
(https://www.gnu.org/software/bash/manual/bashref.html#index-set)
> Exit immediately if a pipeline (see Pipelines), which may consist of a
> single simple command (see Simple Commands), a list (see Lists), or a
> compound command (see Compound Commands) returns a non-zero status.
> The shell does not exit if the command that fails is part of the
> command list immediately following a while or until keyword, part of
> the test in an if statement, part of any command executed in a && or
> || list except the command following the final && or ||, any command
> in a pipeline but the last, or if the command’s return status is being
> inverted with !. If a compound command other than a subshell returns a
> non-zero status because a command failed while -e was being ignored,
> the shell does not exit.
Additionally, further down:
> If a compound command or shell function executes in a context where -e
> is being ignored, none of the commands executed within the compound
> command or function body will be affected by the -e setting, even if
> -e is set and a command returns a failure status. If a compound
> command or shell function sets -e while executing in a context where
> -e is ignored, that setting will not have any effect until the
> compound command or the command containing the function call

Thus, the only way to have our `.integration-daemon-stop` script
actually run appropriately to clean up our daemon on test/script failure
is to use `trap ... EXIT`, which we traditionally avoid because it does
not have any stacking capabilities, but in this case is a reasonable
compromise because it's going to be the only script using it (for now,
at least; we can evaluate more complex solutions in the future if they
actually become necessary).
The alternatives were much less reasonable. One is to have the entire
complex chains in any script wanting to use `.integration-daemon-start`
/ `.integration-daemon-stop` be chained together with `&&` in an `if`
block, which is untenable. The other I could think of was taking the
body of these scripts out into separate scripts, essentially meaning
we'd need two files for each of these, which further complicates the
maintenance.
Add to that the fact that our `trap ... EXIT` is scoped to the enclosing
subshell (`( ... )`) and we're in even more reasonable territory with
this pattern.

https://www.kali.org/ is a Debian derivative. This script completes
succesfully using the Debian install path

This is a symlink to the latest "bundle" that was assembled. For example, if `VERSION` is currently `1.5.0-dev`, then `bundles/latest` will be a symlink to `bundles/1.5.0-dev` after an attempted build.
One interesting property of this is that after a successful `binary` build, we can `./bundles/latest/binary/docker -v` and get back something like `Docker version 1.5.0-dev, build 3ff6723-dirty`.

This will assure that the install script will not
begin executing until after it has been downloaded should
it be utilized in a 'curl | bash' workflow.

Docker does not know about our named cpuacct,cpu,cpuset cgroup
hierarchy with multiple subsystems in it. So to use them with docker
in integration-cli test TestRunWithCpuset inside docker container
we need to add symlinks to them in hack/dind script.
Example:
old version of parser will do:
cat /proc/1/cgroup
11:cpu,cpuacct,name=my_cpu_cpuacct:/
...
and create and mount this hierarchy to directory
/cgroup/cpu,cpuacct,name=my_cpu_cpuacct/
so docker cannot find it because it has strange name
in new parser directory will be same as on host
/cgroup/my_cpu_cpuacct
and have symlinks for docker to find it
/cgroup/cpu -> /cgroup/my_cpu_cpuacct
/cgroup/cpuacct -> /cgroup/my_cpu_cpuacct
in other case if where is no name
cat /proc/1/cgroup
11:cpu,cpuacct:/
...
mount will be same for both parsers
/cgroup/cpu,cpuacct
and new one will also create symlinks
/cgroup/cpu -> /cgroup/cpu,cpuacct
/cgroup/cpuacct -> /cgroup/cpu,cpuacct

The validation script from #10681 is too pedantic, and does not handle
well situations like:
```
cat <<EOF # or <<-EOF
Whether the leading whitespace is stripped out or not by bash
it should still be considered as valid.
EOF
```

For positerity (largely of packagers) lets leave around the generated
version files that happen during build.
They're already ignored in git, and recreated on every build.
