I checked with FNAL with 2 of the sites on which Jing was having 
problems with. As I suspected the siteadmin confirmed that the two 
gatekeepers in question were running NFS-lite and do not respect the RSL 
initial directory variable. The lack of support of initialdir on some 
OSG sites is known issue and it does break compatibility.

Also, is there a way (some parameter we specify), so that swift not to 
set the initialdir parameter. This way the job can finish in what ever 
directory it gets dumped to by the batch system and then possibly copy 
files over to expected location in the $OSG_DATA directory.

Thanks,
Anand
