Jan,
I agree that it would be better not to assume which shell.
Something like what has been done with the executable would suffice:
(**Hypothetical syntax follows**)
<prologue>
<executable>/bin/bash</executable>
<argument>-c</argument>
<argument>my bash shell script</argument>
</prologue>
With the understanding that this is to be executed on a single node
immediately before the cluster executable is spawned on the compute nodes.
This (with a matching epilogue) would give the users the functionality
they have had with conventional batch scripts.
Cheers!
