Subject: [Buildroot] [RFC 1/6] Move mounting /sys from fstab to inittab
Date: Tue, 8 Sep 2015 23:28:49 +0200 [thread overview]
Message-ID: <1441747734-18730-2-git-send-email-luca@lucaceresoli.net> (raw)
In-Reply-To: <1441747734-18730-1-git-send-email-luca@lucaceresoli.net>
We are going to launch mdev from inittab, to have dynamic /dev without
devtmpfs. However, mdev needs /sys to detect devices.
So, mount /sys before the place where mdev will be activated.
