> Agents use the role name in the file system path for persistent volumes: a persistent volume is written to {{work_dir/volumes/roles/<role-name>/<persistence-id>}}. When using hierarchical roles, {{role-name}} might contain slashes. It seems like there are three options here:
> # When converting the role name into the file system path, escape any slashes that appear.
> # Hash the role name before using it in the file system path.
> # Create a directory hierarchy that corresponds to the nesting in the role name. So a volume for role {{a/b/c/d}} would be stored in {{roles/a/b/c/d/<persistence-id>}}.
> If we adopt #3, we'd probably also want to cleanup the filesystem when a volume is removed.
