* Support Monterey
* Run "softwareupdate" on vanilla images
* Install Command Line Tools for Xcode
* Run Ansible after password-less sudo is configured
* Don't use SFTP
* Fix Ansible playbook path
* No updates are available → No new software available
* stderr_lines → stderr
* Dynamically resolve MACOS_NUMBER
