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