Thanx to

Sjolshagen, Thomas (Tru64 UNIX Eng.)" [Thomas.Sjolshagen@hp.com],
"tsh@mrc-lmb.cam.ac.uk" [tsh@mrc-lmb.cam.ac.uk]

The options suggested were

1. use RIS and Install Clone using install.cdf files to replicate machines
2. We can also boot through genvmunix and

ON THE TARGET ROOT FILESYSTEM:
   delete /etc/dec_*
   delete /etc/dfsc.dat
   touch /etc/dfsc.dat
   delete /dev/disk/*
          /dev/rdisk/*
          /dev/tape/*
          /dev/ntape/*

 Halt the machine and:
>>> set auto_action halt
>>> set bootdef_dev ""
>>> boot dka0 -flags s -file /genvmunix #assuming root is on dka0

 When booted:
   mountroot #mount the root filesystem
   dsfmgr -K #create 'special' files for all detected devices
   bcheckrc #mount the rest of the filesystems in /etc/fstab

 Edit /etc/hosts #change hostname/ipaddr
        /etc/rc.config
        /etc/sysconfigtab #change swapdevice if necessary

 Build a new kernel if necessary

 Halt, set auto_action to desired state and reboot.

 Fix any complaints from dsf with dsfmgr -F -v

Thanx
Balaji./
