System Install dependancies
===========================

Objective is trivial reinstall of any system in the cluster using
combination of AutoYaST and most recent available replica/backup.

All systems are installed using GRUB network boot floppy:
  PXEboot requires DHCP server: really don't want this on subnet 8.

  Random thought: bootstrap from eth1: 
    Possibility of using netboot floppy to bootstrap off TFTP server/
    Simpifies IPtables on canvas
    Does require use to maintain Mac address => IP address mapping on Canvas.

tftp server: SuSE Linux kernel and initrd, autoyast.xml files.

NFS and/or FTP server for installation and patches
  NB: first thing we do after install is patch, so only worth using Canvas
  as server if we can keep patches up to date. nfs-uxsup is pretty
  reliable, and we can fall back to using an external mirror.
