netboot strategie

Maybe I'm unclear on the exact question you're asking so I'll answer the one I think you're asking, but I'd have thought that a better way to do a reinstall of a client is to set it to boot off the hard-disk first and then have netboot as the second boot device.  Then, one can tell a client to reinstall itself by erasing the master boot record with dd e.g.

dd if=/dev/zero of=/dev/hda bs=512 count=1

and then rebooting the node.  The client will always attempt to boot from local disk first if there's an installed Linux system including after a reinstall.  This method avoids going through the bootserver and also has the added advantge of reinstalling any clients on the network that eat their own hard-disks automatically.

If you have a blank or non-working system, then you should set the NIC as the first boot device but set it back afterwards.

Hope that was relevant
