There is a not-insignificant performance overhead for all containers (if
containerd is a child of Docker, which is the current setup) if rlimits are
set on the main Docker daemon process (because the limits
propogate to all children).
We recommend using cgroups to do container-local accounting.
This applies the change added in 8db61095a3d0bcb0733580734ba5d54bc27a614d
to other init scripts.
Note that nfile cannot be set to unlimited, and the limit
is hardcoded to 1048576 (2^20) , see:

The change to runc in https://github.com/opencontainers/runc/pull/789
was not documented previously. Also say what this affects and clean
up layout of initial table as there was some miscolouration of the
continuation lines.

[carry 24499] Remove "Yes"/"No" and use "true"/"false" consistently in `docker info`

At the moment docker's deprecation policy is 2 release cycles by
default, which is around 5 months. This may not be enough for
production environment and there is a need to extend the
deprecation cycle to 3 releases (see #24494).
This fix updates the docs/deprecated.md and extend the deprecation
cycle to 3 releases.
This fix is related to #24494 and #24534.
This fix fixes#24534.

The output uses tabs, but those don't
translate well to the rendered output in
the docs, so replacing the tabs with spaces.
Also updates the output, because REPLICATED,
and SPREAD are no longer all-caps in the
actual output.

This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process. The default value
for the flag is -500. This will allow the docker daemon to have a
less chance of being killed before containers do. The default value for
processes is 0 with a min/max of -1000/1000.
-500 is a good middle ground because it is less than the default for
most processes and still not -1000 which basically means never kill this
process in an OOM condition on the host machine. The only processes on
my machine that have a score less than -500 are dbus at -900 and sshd
and xfce( my window manager ) at -1000. I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.

The "none" option was not added to the documentation.
This adds an example, and adds additional information
on manually accepting or rejecting a node.

it used to be, trying to find alternative URLs
where possible.
