From 5b7e273aae7594369a1b3942c7d168c96c4768c0 Mon Sep 17 00:00:00 2001 From: Harald Hoyer Date: Mon, 13 Aug 2012 08:00:21 +1000 Subject: [PATCH] udev-rules: prevent systemd from mount devices before they are ready. In the "add" uevent, ATTR{md/array_state} does not exist, so the next rule does not kick in. When an array is assembled incrementally, systemd might see it before it is ready, try to mount it, fail, and give up. Result is that array doesn't get mounted. If we ask udev to tell systemd that it isn't ready yet in this case, systemd waits until it is ready, and all are happy.
