(and set $exec to dockerd instead)
This ensures end users do not need to make any configuration changes
due to the rename from docker to dockerd in version 1.12.

The docker script in contrib/init/sysvinit-redhat will fail silently on
a start if Docker is not installed in the default /usr/bin/ location.
While a non-zero exit code is returned the user will receive no visible
indication (i.e. error message) as to why Docker was not started.
This commit changes the logic so that in the case that the docker
executable is not found in the expected location or the user does not
have execute permissions on the executable appropriate error messages
are now shown to the user as well as exiting with a non-zero exit code

If you have some kind of bogus `other_args` in `/etc/sysconfig/docker` the start script will report "started" but it's full of lies. This enhances the flow so that if the pidfile never shows up (failure to start) you get a proper failure message.
I also added dots for fun.

unshare the mount namespace of the docker daemon to avoid other pids
outside the daemon holding mount references of docker containers.

This change will allow the Docker daemon's init script to wait up to 5
minutes before being forcibly terminated by the initscript. Many
non-trivial containers will take more than the default 3 seconds to
stop, which can result in containers whose rootfs is still mounted and
will not restart when the daemon starts up again, or worse, orphan
processes that are still running.
