 list of space-separated flags. Possible values are:
 
 - empty: counters will never be reset
-- ``power-on``: The ``remaining_attempts`` counters of all enabled boot targets are reset
-  after a ``power-on`` reset (``$global.system.reset="POR"``). This means after a power
-  cycle all boot targets will be tried again for the configured number of retries.
-- ``all-zero``: The ``remaining_attempts`` counters of all enabled boot targets are
-  reset when none of them has any ``remaining_attempts`` left.

+  (``$global.system.reset="POR"``) is detected, the ``remaining_attempts``
+  counters of all enabled targets are reset to their defaults.
+  This means after a power cycle all boot targets will be tried again for the configured number of retries.
+- ``all-zero``: When the bootchooser starts and the ``remaining_attempts``
