how do turn on NFSSERVER service at boot up?

After bootinup up, to start the NFS service, I need to execute the following command:

/etc/init.d/nfsserver start

How do I start this automatically at boot up? Thanks.

/sbin/chkconfig --set nfsserver on

Or: YaST > System > System Services (Runlevel). Look for nfsserver and Enable.
