+From 722d31dc8823090b651b103f0194b6380f2d458e Mon Sep 17 00:00:00 2001
+From: Alexandre Rostovtsev <tetromino@gentoo.org>
+Date: Tue, 25 Sep 2012 22:30:29 -0400
+Subject: [PATCH] daemonize so that the boot process can continue
+
+Gentoo bug: #236701
+
+Based on original patch by Dan Nicholson <dbn.lists@gmail.com> and
+Gilles Dartiguelongue <eva@gentoo.org>.
+
+Fork gdm-binary, except when -nodaemon is used
+
+Makes the gdm main binary fork and daemonize unless the -nodaemon or
+--nodaemon options are used. Provides compatibility with xdm. Fixes
+bug #550170.
+
+In daemonized mode, start a new process group, and kill it in our signal
+handlers, so that killing gdm kills its spawned processes, and so that
+"/etc/init.d/xdm stop" actually works.
