+# You _might_ decide that --limit looks cleaner and you use that a lot already,

 # Note that someone probably wants to run:
-# ansible -m shell -a 'dnf --refresh -y update; (rkhunter --propupd || true)' 'all:!copr*:!openqa*:!ocp*:!worker*'
-# ...during an outage. Note that doing more than one vmhost at once isn't

+# ...before an outage.
+# NOTE: that rebooting more than one vmhost at once isn't
 # easily safe, because some vmhost will want another to be up while they reboot.

 # Also:
 # ansible ... 'staging:!copr*:!openqa*:!ocp*:!worker*'
 # could be used for staging, but it's not that big.
