From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dave Reisner Subject: [PATCH] mdadm: autodetect being run in an initramfs Date: Thu, 27 Sep 2012 10:41:03 -0400 Message-ID: <1348756863-21081-1-git-send-email-dreisner@archlinux.org> Return-path: Sender: linux-raid-owner@vger.kernel.org To: linux-raid@vger.kernel.org Cc: teg@jklm.no, dreisner@archlinux.org List-Id: linux-raid.ids Key off of the existance of /etc/initrd-release as an indicator that mdadm is running in early userspace and set the __offroot flag. This allows the same udev-based assembly rules to be valid both off and on root and, moreover, will propagate to mdmon, should it need to be started.
