The basic operational model is as follows.

* We turn the nodes on.

* Since there is nothing on the disks, they will fall through to
  booting from the PXE and will boot the newnode MFS. They all check
  in.

* We run Jon's script that adds the nodes. They are now in hwdown,
  still nothing on the disks.

* We run my script, which is driven from a datafile we are supposed to
  get from HP. This script has the ilomac, ilopswd, control mac. I
  will add another column initially; the permanent IP to assign to the
  ilo. This script does:

 + Reads the datafile to get all the stuff.
 + Reads the dhcpd.leases file to find the temporary IPs of the ilos.
 + Finds the corresponding nodes in the DB.
 + Sends over an XML file that does the following:
     - Add the elabman user.
     - Add local root's dsa pub key to the new elabman user.
     - Add Utah's root dsa key to the Administrator user
     - Sets the power on mode to auto (so that the node turns on!).
     - Sets the idle timeout to 2 hours.
 + Sets the bootorder so that PXE is first. This has to be done
   with ssh and some expect stuff I culled from power_ilo. Sigh.
 + Calls out to another script that adds the ilo interface to the
   DB (this is the management_iface script I did last month).
 + Sends another XML file that tells the ilo to reset itself, so that
   it picks up its permanent IP address.

* Now we can free the nodes from hwdown.
