	Hello hello,

	I've just recently run into some nfs problems that I hope someone can
shed some light on for me. First off,  I'm still running hpux 6.5 on a cluster 
configuration with a 340 server and a 340 diskless client. And I have a file
system nfs mounted from an ultrix machine, with -r=0 (root being root).

	My problem is that when someone on the diskless cnode tries to do 
a Make of some code, the make creashes with the following error message coming 
from getwd() :

getwd: cannot open ..

But if you execute the same make under the same cirumstance from the server, 
everything runs fine and the make builds successfully.  I can also generate 
the same getwd error message under different circumsatance (i.e. 'su' doing 
a fast login, no "-" option). And I cann't get an `ls' of the NFS mounted fs 
when I ftp to the diskless client (it doesn't return a single filename).  

	This seems to be the familiar getwd bug that I've run accross before 
but does anyone have a patch, or just simply now what's going on ? The 
permissions all seem ok (owned by root, diectories are all 755, etc). 
Or better yet, is this fixed in 7.0 ?

	Thanks for ideas,
	greg
