[K12OSN] NFS fails to start

[Kenneth Lundström]

Hi,

sounds like an Windows fix, please reinstall :=) But that is just what I 
decided needs to be done, I emailed the client and will head out to 
client tomorrow morning.

One strange thing I noticed by mistake is the dates on folders.

[root at ltsp tmp]# ll /opt/
total 4
drwxr-xr-x. 5 root root 4096 Mar 17  1913 ltsp

LTSP was hardly thought of 1913. I tried to look in different logs but 
can't see any file errors. But I see some folders being dated to 1913. 
Should matter for NFS, but if filesystem is that messed up no wonder NFS 
doesn't work.
