I have a lot of different machines performing different tasks, but very few machines running the same tasks as another one, so it's definitely a case of pets rather than cattle for the bulk of work.

Automation is a preseed, a script to do user management, and a phone home package which sends information about the machine back to a central server. My main bugbear about ansible is it leaves very little trace -- it runs by copying a file to the remote server in /tmp, executing the file (sometimes under sudo), and then deleting it. I get the notification on syslog that ansible has logged in and done something, but I don't know what, so I rely on the ansible Compared to when someone manually goes in and does something like "sudo vi /etc/resolv.conf" - even if doing it en-mass, I get notification that joebloggs logged in at 14:53 on Wednesday and edited resolv.conf.

Ansible means I need to look at the ansible logs, but even then I don't know exactly what was actually executed on the box.
