If I see "SSHD: Use OpenSSH" on usbnetwork, I should select that option so it'll default to dropbear?

Also, your readme states: "The pubkeys are stored, in OpenSSH format, in usbnet/etc/authorized_keys (i.e., the very same file that's usually found as ~/.ssh/authorized_keys on real *nix OpenSSH setups)."

Yet there is no authorized_keys file in the [kindleroot]/usbnet/etc/ ; I assume I am to create one?

I assume all the keys that make ssh'ing over USB won't be messed up by me creating an authorized_keys file?
