Role Variables

unbound_flags

This variable is used for overriding defaults for startup scripts. In Debian variants, the value is the content of /etc/default/unbound. In RedHat variants, it is the content of /etc/sysconfig/unbound. In FreeBSD, it is the content of /etc/rc.conf.d/unbound. In OpenBSD, the value is passed to rcctl set unbound flags.

Notes about unbound_force_flush_handlers

When unbound_force_flush_handlers is yes, all the pending handlers are flushed, meaning, all pending handlers on other hosts in the play, including ones that do not play this role, are executed. You have to ensure this side-effect will not cause issues in the play. One solution is, do not run a play with this role on other hosts. The other one is to ensure all other roles or tasks before this role will not trigger any handler.

meta ansible module does not support when. If you set unbound_force_flush_handlers to yes, ansible warns that "flush_handlers task does not support when conditional". There is no way to suppress the warning. See also issue 4131.
