+*--sshcopyid*::
+
+ Use locally available public keys to authorise root login on the target system.
+ Similar to ssh-copy-id(1) (without the -i option) it checks if `ssh-add -L`
+ provides any output, and if so those keys are appended to
+ _/root/.ssh/authorized_keys_ (creating the file and directory (with mode 0700)).
