Currently, the broker denies any non-local exec request on rank 0 due to security considerations on multi-user instances where the rank 0 broker is typically running on a locked down management node. However, in a single user instance such as a batch job, this configuration is unnecessary and may prevent certain use cases such as execution of commands that can only run on rank 0 from other broker ranks. (flux filemap map is the use case that precipitated this issue report)
Consider somehow detecting single-user mode and disabling this check in that case.
