+Subject: [PATCH] runc-docker: Allow "run start ..." to daemonize with $SIGUSR1_PARENT_PID
+
+The runc-docker has all the code in it to properly run a stop hook if
+you use it in the foreground. It doesn't work in the back ground
+because there is no way for a golang application to fork a child exit
+out of the parent process because all the golang threads stay with the
+parent.
+
+This patch has three parts that happen ONLY when $SIGUSR1_PARENT_PID
+is set.
+
+1) The code was copied which performs the normal the signal handling
+ block which is used for the foreground operation of runc.
+
+2) At the point where runc start would normally exit, it closes
+ stdin/stdout/stderr so it would be possible to daemonize "runc start ...".
+
+3) The code to send a SIGUSR1 to the parent process was added. The
+ idea being that a parent process would simply exit at that point
+ because it was blocking until runc performed everything it was
+ required to perform.
