The only place the user's default device and directory is stored is in
SYSUAF.DAT.  Any method you choose for determining the device must have read
access to this file.  This doesn't require "operator privileges" - READALL,
SYSPRV, or BYPASS will suffice, or you can install the image you use to get the
default with privilege so that the end user doesn't need them.

What you can do is pick up the GETUAI utility off of an FTP site (see Ric
Steinberger's monthly posting for locations).  Then you can do stuff as simple
as:
	$ INSTALL GETUAI/PRIV=READALL	! do at system boot time
	$ GETUAI/DEFAULT=joesdir JOE
	$ SET DEFAULT 'joesdir'

It's interesting to note that the following does *not* work (unfortunately):
	$ POSIX
	psx> pwd
	/disk1/fred
	psx> cd ~joe
	psx> pwd
	/disk1/joe
	psx> ^d
	$ SHOW DEFAULT
	DISK1:[FRED]
