TODO for update-cluster
=======================

* support several NICs, and generate IP for several NIC at the same time.
  -- different NICs may have different hostnames, and they will have different 
  IPs and MAC addresses, thus they will need their individual 
  hostname/IP/MAC pair; which is, a new "host" entry.

* dh_installupdatecluster

* A suitable way to handle other packages such as spong, diskless etc. without adding extra fields for every node. Maybe a cluster specific single entry such as <spong> <nfsrootbase> etc.

* notes is not a good way to specify master. -- or maybe not. It seems
   to be functional.

* How to treat packages which doesn't want cooperate with update-cluster...
  Make update-cluster-xxx packages ? -- a partial solution. A sysadmin can
  configure in /etc/update-cluster/updatelist/*.updatelist.
  Whether this is a good idea, should be discussed...

* document --bootmaster, and update docs on deprecated options
   (--nfsroot, which nobody actually managed to use).

* document and implement a global header XML -- introduce CDML.
