I have a problem with samba

when i have a boot start i get a message

umount nfs UNUSED

if i loggon as root and use the commando: rcnfs restart/start

i`ve get the error :
Remove Net File System (NFS) UNUSED
Importing Net File System (NFS) UNUSED

There is a config file for NFS (/etc/exports)

But it`s empty ????

can anywhone tell me how to configure it

I have just configured a NFS server but it doesn`t work
at a boot startup

But when i start it in a ternminal logon as root

It works

commando: rcnfs restart
Remove Net File System (NFS) done
Importing Net File System(NFS) done

why doesn`t it work at a boot start

I have a lot of problem`s with boot start
Samba, named, nfs won`t start automatic

i have used the commando`s
# ln -s /usr/sbin/rcsmb /etc/init.d/rc3.d/S20rcsmb
# ln -s /usr/sbin/rcsmb /etc/init.d/rc3.d/K05rcsmb
# ln -s /usr/sbin/rcsmb /etc/init.d/rc5.d/S20rcsmb
# ln -s /usr/sbin/rcsmb /etc/init.d/rc5.d/K05rcsmb

but it still doesn`t work!!!

why??
