Sebastiaan van Stijn 7c63b49df6 Document that ENV vars are not automatically updated
Unlike the entries in `/etc/hosts`, environment-variables for linked
containers are not automatically updated if the linked container is
restarted.

This adds a note to the documentation in;
https://docs.docker.com/userguide/dockerlinks/#environment-variables
and
https://docs.docker.com/reference/run/#env-environment-variables

To make users aware that this is the case and recommends them to use
the `/etc/hosts` entries in stead.

I added this change because users were expecting environment variables
to be updated automatically as well (https://github.com/docker/docker/issues/10164).

Phil Estes 74b009e816 Add backing filesystem info to `docker info` command where applicable
Fixes #9960

This adds the output of a "Backing Filesystem:" entry to `docker info`
to overlay, aufs, and devicemapper graphdrivers. The default list
includes a fairly complete list of common filesystem names from
linux/include/uapi/linux/magic.h, but if the backing filesystem is not
recognized, the code will simply show "<unknown>"

Sebastiaan van Stijn 72aae7c046 Docs: Add note that export doesn't include volume data.
The documentation on `docker export` doesn't mention that
data in volumes is not included in the export.

This adds a note that volumes are not part of the export
and refers to the "Backup, restore, or migrate data volumes"
to give the user some pointers.

Relates to https://github.com/docker/docker/issues/10095

Michael Crosby 221cd67e25 Add --readonly for read only container rootfs
Add a --readonly flag to allow the container's root filesystem to be
mounted as readonly.  This can be used in combination with volumes to
force a container's process to only write to locations that will be
persisted.  This is useful in many cases where the admin controls where
they would like developers to write files and error on any other
locations.

Dan Walsh f4573ee0bc Allow the container to share the PID namespace with the host
We want to be able to use container without the PID namespace.  We basically
want containers that can manage the host os, which I call Super Privileged
Containers.  We eventually would like to get to the point where the only
namespace we use is the MNT namespace to bring the Apps userspace with it.

By eliminating the PID namespace we can get better communication between the
host and the clients and potentially tools like strace and gdb become easier
to use.  We also see tools like libvirtd running within a container telling
systemd to place a VM in a particular cgroup, we need to have communications of the PID.

I don't see us needing to share PID namespaces between containers, since this
is really what docker exec does.

So currently I see us just needing docker run --pid=host

Dan Walsh ea4024d2bd --help option and help command should print to stdout not stderr
--help and help are successful commands so output should not go to error.

    QE teams have requested this change, also users doing docker help | less
    or docker run --help | less would expect this to work.

    Usage statement should only be printed when the user asks for it.
    Errors should print error message and then suggest the docker COMMAND --help
    command to see usage information.

    The current behaviour causes the user to have to search for the error message
    and sometimes scrolls right off the screen.  For example a error on a
    "docker run" command is very difficult to diagnose.

    Finally erros should always exit with a non 0 exit code, if the user
    makes a CLI error.
