From 1e886090cefe26113122a7d59a36a9aec492fef5 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Tue, 20 Apr 2021 14:06:38 +0200 Subject: docs: admin-guide: update description for kernel.hotplug sysctl It's been a few releases since this defaulted to /sbin/hotplug. Update the text, and include pointers to the two CONFIG_UEVENT_HELPER{,_PATH} config knobs whose help text could provide more info, but also hint that the user probably doesn't need to care at all.
