The keyfile worth overriding is the one in kdc.conf. Though using
stash -f would override kdb5_util's -sf argument, there is no reason to
pass both flags to the same invocation.
In any case, the "at startup" language is not really correct.
**stash** [**-f** *keyfile*]
Stores the master principal's keys in a stash file. The **-f**
-argument can be used to override the *keyfile* specified at startup.
+argument can be used to override the *keyfile* specified in
+:ref:`kdc.conf(5)`.
