Notes on Building the Inventory Image

This consists of the following steps:

• Creation of bootable directory via debootstrap
  • Installation of needed packages
  • Installation of Kernel
  • Installation of Inventory Scripts
  • Fixing device naming and driver load order
• NFS server configuration to export it
  • exports are stored in /etc/exports on respository1
  • after editing file, run exportfs -ra
• PXE configuration so a node boots it

• Debootstrap steps
  • create /export/inv_root/inventory_16.04
    • run sudo debootstrap --arch amd64 xenial /export/inv_root/inventory_16.04/
• Chroot into new directory
  • LANG=C.UTF-8 chroot /export/inv_root/inventory_16.04/ /bin/bash
• Install editor
  • vim
• Update /etc/apt/sources.list
