The container-executor process never uses these values in a shell context, but simply adds the entire value as an argument to exec(), which in turn is passed as the argument following {{--tmpfs}} in docker. I have verified that passing in things such as your example results in the mountpoint being literally named: {noformat} /foo/bar || <execute_bad_code> {noformat} This is expected. was (Author: ccondit-target): [~ebadger], the regex is based on the one used for normal mounts.
