From 3b256653ae9ab2cf56b21cb82a8bd2a562397b27 Mon Sep 17 00:00:00 2001 From: Bill Pittman Date: Mon, 21 Jul 2014 11:53:46 -0500 Subject: busybox: mdev: Use mdev.seq /dev/mdev.seq exists to synchronize concurrently running instances of mdev and to ensure that they execute in the proper order. Without this synchronization, it is possible to have inconsistent mount points, to leak device nodes, or to have a node erroneously removed in rapid hotplug scenarios. Enable the use of mdev.seq by creating an empty /dev/mdev.seq at boot.
