sshd requires that the user's authorized_keys, the directory it's in
(~/.ssh) and all its ancestor directories be owned by either the user or
root.

I don't see why / should be owned by bin; bin is intended for system
binaries and libraries, i.e. {,/usr}/{bin,sbin,lib,libexec}, except
those that need to be setuid or setgid.  The directories themselves
should probably still be owned by root:wheel.
