+KDUMP_SSH_IDENTITY
+~~~~~~~~~~~~~~~~~~
 
+List of SSH identity files for public key authentication. If empty, kdump
+will try all standard OpenSSH identities for the 'root' user (rsa, dsa,
+ecdsa, ed25519, in this order). The path to every identity file is relative
+to +~root/.ssh+, or an absolute path can be given.
+
+Example: "/root/.ssh/id_kdump_rsa"
