How to mount NFS volume at Boot time in Linux?

It seems very basic thing - however, coming from Solaris background, it was always a puzzle why Linux was not able to mount my NFS volumes the way it was mounting in Solaris. Basically, the only difference is "_netdev" keyword - which tells Linux that this device should be mounted AFTER network services are UP. To work around this, I even used a custom run-control script at /etc/rc3.d to mount it later. Now that I found "_netdev" keyword - I know that I am never going to use any workarounds for my NFS volumes. :)
