How to permanently detach Pro instances

1. Modify the client configuration file, normally /etc/ubuntu-advantage/uaclient.conf, to contain:

   features:
     disable_auto_attach: true

2. Run sudo pro detach --assume-yes

Explanation

On Pro instances, a pro detach won't permanently detach the instance since it will be automatically re-attached on the next boot (on non-GCE instances) or immediately (on GCE instances due to the daemon).

The configuration in step 1 will prevent the daemon and the autoattach service from automatically re-attaching at next boot.

If you want to allow the instance to automatically re-attach by itself, then remove or set disable_auto_attach to false in the configuration file.
