> Currently, all mounts in a container are marked as 'slave' by default. However, for some cases, we may want mounts under certain directory in a container to be propagate back to the root mount namespace. This is useful for the case where we want the mounts to survive container failures.
> See more documentation about mount propagation in:
> https://www.kernel.org/doc/Documentation/filesystems/sharedsubtree.txt
> Given mount propagation is very hard for users to understand, probably worth limiting this to just host volumes because we only see use case for that at the moment.
