+Subject: [PATCH] dmeventd configurable idle exit time
+
+dmeventd nominally exits after 1 hour of idle time. There are use cases for
+this, esp. with socket activation, but also cases where users don't expect
+dmeventd to exit.
+
+Provide a tuning knob via environment variable, DMEVENTD_IDLE_EXIT_TIMEOUT,
+that can be -1 to not exit, or a configurable time for different idle exit.
+
+Signed-off-by: Robin H. Johnson <robbat2@gentoo.org>
+Fixes: https://bugs.gentoo.org/682556
