Persistent Keyring Expiry

This file defines an interval, in seconds, to which the persistent keyring’s expiration timer is reset each time the keyring is accessed (via keyctl_get_persistent(3) or the keyctl(2) KEYCTL_GET_PERSISTENT operation.)

The default value in this file is 259200 (i.e., 3 days).
