Basic setup of Ubuntu server

This is my personal memo for setting up new Ubuntu servers in my environment. It may not be appropriate for your environment but feel free to use it as a starting point.

During setup

  1. Accept all defaults except as listed here.
  2. For the machine name use the full name including the local domain, e.g. new-server.local.domain
  3. Add a user for all build tasks, name is Build, username is build
  4. Do not encrypt the home directory.
  5. Do not use LVM
