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.'
