As far as I can tell, authorized_keys2 has been a deprecated file for six or so years now[1]. Given that it doesn't appear that any of the distros in the Distro Wizard are anywhere near that old, why is it Lish still creates authorized_keys2 files[2] instead of using the recommended authorized_keys name? Granted authorized_keys2 is one of those things that may linger forever, but I don't consider that an excuse not to promote the current style... especially considering its only a one character change.
