Hi Dave,
I think you may be okay with this , providing the password
file(or nis) has the correct entry on each worker node, ie
/home/edg/wpsix001 then everything should just work. I believe
scotgrid has something similar. $HOME will be evaluated on
each node.
If it does not work then altering the Users-cfg.h file to use
/home/edg rather than home is the sure way to solve this.
