From 7934779a69f1184f29d786b89e77dd14519bd226 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Thu, 14 Jan 2010 22:49:39 +0100 Subject: [PATCH] Driver-Core: disable /sbin/hotplug by default No recent mainstream system uses the /sbin/hotplug fork-bomb any more. Disable it by default to reflect how it is used these days.
