No, but I'm fairly sure Werner did not realise you were using a smartcard when
he wrote that. Obviously, I can't look into the man's mind, but that's my guess.

For regular, on-disk keys, it is necessary to add the keygrip to sshcontrol. For
smartcards, it's automatically added when the smartcard is inserted. I guess it
fits with automatically added secret key stubs when the smartcard is inserted
(to use a smartcard on a fresh PC, import your own public key, insert your
smartcard, and you're done).



I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
