Build a custom Ubuntu base box for Terraform+Proxmox by downloading, extracting, tweaking, and packaging the stock Ubuntu ISO.

Based on: https://github.com/yep/vagrant-ubuntu

• curl(1).
• m4(1).
• mkisofs(1) from the cdrtools package available from MacPorts or Homebrew.

The results are bootable ISO images and so should run on any i386 or amd64 hardware. They are only tested in Proxmox.

• Configurable default user with SSH key and sudoer NOPASSWD access
• The system clock is set to UTC
• Auto partition virtual disk (/dev/vda) with LVM
• OpenSSH server is installed
• Bring up only eth1 for flexible user-net SSH port forwarding
• Includes script to auto-resize partitions to the current size of vitual disk /etc/auto_resize_vda.sh

Edit configuration in

config.sh
