Failed starting rpc.mountd

[Reuben D. Budiardja]

Hello,
When I boot my machine, I often get something like the following :

Starting NFS mountd:                                       [  Failed  ]

immediately after the booting process finish, I can issue "service nfs 
restart" as root and then NFS starts correctly. Any idea what might cause 
this ? 

Here is from my /var/log/messages during boot:

Jul 26 09:07:28 defiant exportfs[2520]: /etc/exports [1]: No 'sync' or 'async' 
option specified for export "192.168.0.100/255.255.255.0:/home/multimedia".   
Assuming default behaviour ('sync').   NOTE: this default has changed from 
previous versions
Jul 26 09:07:28 defiant kernel: Installing knfsd (copyright (C) 1996

Jul 26 09:07:28 defiant rpc.idmapd: nfsdreopen: Opening '' failed: errno 2 (No 
such file or directory)

And /etc/exports:
/home/multimedia	192.168.0.100/255.255.255.0(rw,no_root_squash)

Thanks for any help.
