Hi List,

some of the highlights of 6.4 (and I cite the announcement):
"New and much-improved NFS Lock Manager (NLM) client".

Sounds great. My old nfs-box serving pxe clients is still at 6.3. Clients 
run 7.x and 8. 

On the clients run postfix, but having installed 8.0 on the nfs-server, 
postfix complains:

Apr 18 19:49:45 mostrd postfix/cleanup[805]: fatal: select lock: 
Permission denied

Further testing revealed: as of 6.4 something has changed. Trying to stuff 
in the old nfs, rpc.statd, etc etc into the 8.0 src proves 
to be not that simple (hah).

Now, what has been changed precisely ? All other things on the client run  
okay (yeah, well dovecot is in companion of postfix iirc. tested a few 
months ago).

Am I missing some magic knob ? Or are both postfix and dovecot 
handles to their locking plain wrong (now) and do I need to patch them.

Looking for some clue where to go now ;-)

Regards,
Robert
