>
> DockerLinuxContainerRuntime bind mounts the filecache and usercache
> directories into the container to allow tasks to access entries in the
> distributed cache. However it only bind mounts directories on disks that
> are considered good, and disks that are full or bad are not in that list. If
> a container tries to run with a distributed cache entry that has been
> previously localized to a disk that is now considered full/bad, the dist
> cache directory will _not_ be bind-mounted into the container's filesystem
> namespace. At that point any symlinks in the container's current working
> directory that point to those disks will reference invalid paths.
