I remember getting something similar when the file and directory  
permissions were not set properly (and/or export permissions).  So  
even when the boot directory exists, correct permissions to view or  
use it were not set properly.  I didnt track down any information  
regarding the exact settings required for diskless boot, however when  
I copied the nfs export to a new export and chmod to world readable,  
then i got past the gui errors.  I stepped back, adjusted the boot and  
then got the diskless client booting, however there were a few other  
things regarding permissions, home directories, and whatnot that also  
caused failure to boot, or get x started.  Ill check out the wiki and  
see if anyone posted the information for file permissions, would be  
nice to get this going again.'
