Comment:
After updating to Django 1.0 I got this traceback where the admin tries to
write stuff to a NFS mount. I'm not 100% sure it's the the same issue that
this ticket was about, but it fails at the line of the fix ...
* OS: Debian Etch
* export options: (rw,sync,no_subtree_check)
* nfsd and client nfs tools versions: 1.0.10-6+etch.1
* options from the mount:
rw,vers=3,rsize=32768,wsize=32768,hard,intr,proto=tcp,timeo=600,retrans=2,sec=sys,addr=vm1
