Procedure for creating a new base image for kadeploy

1. Boot the machine with a live cd. If you are in a remote machine you'll probably new ILO access or something similar. 2. Install the new system selecting the existing swap and /dev/sda4 partitions. You can start from scratch deleting all partitions and recreating them but it's higly discouraged.

NOTE: In an standard kadeploy setup /dev/sda4 is the deployment partition and /dev/sda2 is the base system partition

3. Create the update-host-name script in the adequate directory, for a debian based system is in /etc/dhcp/dhclient-exit-hooks.d/

File: /etc/dhcp/dhclient-exit-hooks.d/update-host-name.sh

#!/bin/sh
# update-host-name, update hostname with host-name and domain-name

if [ -n "$new_host_name" ]; then
  if [ -n "$new_domain_name" ]; then
    hostname="${new_host_name}.${new_domain_name}"
  else
    hostname="${new_host_name}"
  fi

  echo "$hostname" > /etc/hostname 2>/dev/null
  hostname "$hostname"
fi

4. Make sure that an SSH server is running.

5. Follow the procedure detailed in Deploy Procedure in Kadeploy 3 and OAR for saving an image file.
