.. note::
When used together with "serial", tasks marked as "run_once" will be run on one host in *each* serial batch.
If it's crucial that the task is run only once regardless of "serial" mode, use
:code:`when: inventory_hostname == ansible_play_hosts[0]` construct.
:code:`when: inventory_hostname == ansible_play_hosts_all[0]` construct.
.. note::
Any conditional (i.e `when:`) will use the variables of the 'first host' to decide if the task runs or not, no other hosts will be tested.
