Upgrading an OpenSSI Cluster from Prior Releases on Debian 3.1(Sarge)
====================================================================
These instructions describe how to upgrade an OpenSSI 
cluster on Debian Testing (3.1, Sarge) from  previous
releases of openssi. Openssi can be upgraded on Debian 
using apt-get utility by following the steps mentioned below.

1. Add following entries to '/etc/apt/sources.list'
   in addition to entries used for Debian installation. 

  deb http://deb.openssi.org/v2 ./
  deb-src http://deb.openssi.org/v2 ./

2. Add following entries to /etc/apt/preferences if it 
  is not already there. 

  Package: * 
  Pin: origin deb.openssi.org
  Pin-Priority: 1001

3. Configure http proxy if it is not already configured.
   In the bash shell , you can export environment variable 
   "http_proxy" by setting its value to local proxy server.

4. Add necessary drivers list to 
  "/etc/mkinitrd/modules"(if it is not there already). 
  Most important drivers are network drivers, depending upon 
  the network cards used in the participating nodes in the 
  cluster (Ex: e100, eepro100 etc.), which would be used while 
  booting cluster nodes. If it is already there , no problem.

5. If dhcp3 is not installed on the system, please install
  dhcp3-server package 

6. Execute:

  # apt-get update 

  # apt-get dist-upgrade

  This would upgrade openssi from previous release to 
  new release . 

7. Reboot the cluster .

  NOTE: It has been observed that some time tftp server 
  will not respond to request once it already responded 
  to client's request. So restart the inetd on the init 
  node if client could get IP address , but could not 
  continue booting.

  # invoke-rc.d inetd restart

8. Create symlinks for each node in /dev as `ln -s /dev /dev/n`  
   where as 'n' stands for each node number in the cluster.
