Not really, the execute node knows what it can support, thus needs to 
advertise this to the user, thus STARTD_ATTRS seemed like the correct place 
(and is, see below)

getenv imports the environment of the user when submitting the job, correct? 
Thus, how should the submit machine know.

Greg Thain had a much, much simpler solution (thank you very much for that!)

$$(VARIABLE) in the submit file will pick up the STARTD_ATTRS I already set. 
Works beautifully.

Caveat: you need to set this variable everywhere or make sure by using proper 
requirements, to steer only to machines which supports this (but then there 
seems to be another problem, see my next email), otherwise your jobs will go 
into hold state.
