Nice work!
Saved me a massive headache because the solution given by Ansible here doesn't work... You should let them know of yours!
Thanks
Thank you @drrzmr!!! I was trying to get something functional put together from three examples, none of which worked on their own. This write-up is doing a favor for the entire Ansible community. Much appreciated.

Hello,
Good work, but unfortunatelly I get this:
"bash: shutdown: command not found", "stdout": "", "stdout_lines": [], "warnings": []}
And the playbook looks like this:
`---
remote_user: razvan
become: True
become_method: su
tasks:
name: install nmap
yum: pkg=nmap state=latest
name: 'reboot...'
shell: nohup bash -c 'sleep 2 && shutdown -r now "Instalat NMAP"'
async: 0
poll: 0
register: rebooting
name: 'waiting...'
local_action: wait_for host=web1 search_regex='OpenSSH' port=22 state='started' delay=30 timeout=300
become: True
become_method: su
when: rebooting|changed`
