Message-Id: <1257344795-8665-3-git-send-email-vapier@gentoo.org> Date: Wed, 4 Nov 2009 09:26:35 -0500 From: Mike Frysinger <vapier@...too.org> To: stephen.hemminger@...tta.com, netdev@...r.kernel.org Subject: [PATCH] ifstat/nstat/rtacct: use daemon() A bunch of misc utils basically reimplement the daemon() function (the whole fork/close/chdir/etc...). Rather than do that, use daemon() as that will work under nommu Linux systems that lack fork().
