Description

To address this TODO in the code:

src/slave/containerizer/isolators/filesystem/linux.cpp +122


// TODO(jieyu): Currently, we don't check if the slave's work_dir
// mount is a shared mount or not. We just assume it is. We cannot
// simply mark the slave as shared again because that will create a
// new peer group for the mounts. This is a temporary workaround for
// now while we are thinking about fixes.
