Changing the location of persistent_store

[purpleguitar]

Is there a way to direct SGS to place its persistent_store database directory elsewhere?

EDIT:  In working around the issue above, I came across a frustrating bug:  "persistent" is spelled incorrectly!  When the server starts, a directory is created called "persistant_store".  Hopefully this will be fixed in a later release.  At least now I know why my ant script failed to remove my DB files when I tried to remove "persistent_store".
