Hi Hans!<br><br>Yeah! Direct netboot is a very nice idea too... I can&#39;t to it with one kind of server I&#39;ll have but with the clustered ones that I&#39;ll be nice! To improve reliability I could make a copy of a healthy image to the node&#39;s hard drive every time it boots, so it&#39;s not dependent on a  NFS server all the time (just to boot).
