+Subject: [PATCH] babeld: close stdout once the background daemon is created
+
+Upstream-Status: pending
+
+Once babald becomes a background daemon, it should not output information to
+stdout, so need to close stdout.
+
+In fact, other daemons close their stdout when they run into background, like
+ospfd, isisd and bgpd, by calling daemon() which is in lib/daemon.c
+
+Closing the stdout can fix a tee hang issue { #/usr/sbin/babeld -d |tee tmp }
+
