That enables them if they are the kernel console and is probably a user friendliness improvement. Sorry for the delay... I think that's a very good idea. I wasn't even aware of this flag. We could mark all ttyu# lines as onifconsole by default across all architectures and if that unifies the contents of the /etc/ttys file, revert back to a single one... -- Marcel Moolenaar marcel@xcllnt.net [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org iEYEARECAAYFAlNm0EsACgkQpgWlLWHuifaQ7gCeJDhhtCUrpB66NhKw4zxfatRP 9sIAnAjAwQ6H12AXArtgsvx0AoWSU20c =DilW -----END PGP SIGNATURE-----
