---------------------------------
[~ebadger] Any other concern about this feature? I will commit this, if there
is no other objection.
> Add support for a volume blacklist for docker containers

> Project: Hadoop YARN

> Docker supports bind mounting host directories into containers. Work is
> underway to allow admins to configure a whilelist of volume mounts. While
> this is a much needed and useful feature, it opens the door for
> misconfiguration that may lead to users being able to compromise or crash the
> system.
> One example would be allowing users to mount /run from a host running
> systemd, and then running systemd in that container, rendering the host
> mostly unusable.
> This issue is to add support for a default blacklist. The default blacklist
> would be where we put files and directories that if mounted into a container,
> are likely to have negative consequences. Users are encouraged not to remove
> items from the default blacklist, but may do so if necessary.
