From mboxrd@z Thu Jan 1 00:00:00 1970 From: Josh Triplett Subject: [PATCH RESEND] uts: Set default hostname to "localhost", rather than "(none)" Date: Sun, 10 Apr 2011 22:01:59 -0700 Message-ID: <20110411050155.GA2507@feather> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii To: David Miller , netdev@vger.kernel.org, "Serge E. Hallyn" , Andrew Morton , Linus Torvalds Received: from relay3-d.mail.gandi.net ([217.70.183.195]:51381 "EHLO relay3-d.mail.gandi.net" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752412Ab1DKFIu (ORCPT ); Mon, 11 Apr 2011 01:08:50 -0400 Content-Disposition: inline Sender: netdev-owner@vger.kernel.org List-ID: The "hostname" tool falls back to setting the hostname to "localhost" if /etc/hostname does not exist. Distribution init scripts have the same fallback. However, if userspace never calls sethostname, such as when booting with init=/bin/sh, or otherwise booting a minimal system without the usual init scripts, the default hostname of "(none)" remains, unhelpfully appearing in various places such as prompts ("root@(none):~#") and logs. Furthrmore, "(none)" doesn't typically resolve to anything useful, while "localhost" does. Change the default hostname to "localhost". This removes the need for the standard fallback, provides a useful default for systems that never call sethostname, and makes minimal systems that much more useful with less configuration. Signed-off-by: Josh Triplett --- Looked at "(none)" one too many times, and figured I ought to do something about it. Resending, and adding CCs for networking and UTS. include/linux/uts.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/include/linux/uts.h b/include/linux/uts.h index 73eb1ed..610bec2 100644 --- a/include/linux/uts.h +++ b/include/linux/uts.h @@ -9,7 +9,7 @@ #endif #ifndef UTS_NODENAME -#define UTS_NODENAME "(none)" /* set by sethostname() */ +#define UTS_NODENAME "localhost" /* set by sethostname() */ #endif #ifndef UTS_DOMAINNAME -- 1.7.4.1
