File 0001-systemd-mount-set-device-timeout-from-the-kernel-com.patch of Package systemd-mini

From a7ef787c33aa8d12852a176cdeb1ecdb39cf56fe Mon Sep 17 00:00:00 2001

Subject: [PATCH] systemd-mount: set device timeout from the kernel commandline

On some systems device probing can take longer than the predefined
device timeout. This patch adds a kernel commandline option
'mount.timeout' and 'rd.timeout' for allowing to modify the
default device timeout.
