local-fs-pre.target serves as a separator between the code for
detecting block devices and systemd's fsck/mount logic. This
patch ensures that multipathd is started before local-fs-pre.target
in the initrd. By adding a "Wants=" line for local-fs-pre.target,
it makes sure that this target is started at all.

SLES11 provided a kernel commandline option 'multipath=off',
so dracut should be parsing the option, too.

We need to wait until udev has processed all events, otherwise we'll
risk of misdetecting devices. This might cause a temporary interruption
during which multipath removes a device-mapper device, which then
causes a booting failure.

If rootfs is on multipath, but platform does not have an /etc/multipath.conf
file which is not urgently needed, they system will not boot, due to:
multipathd is not started and rootfs and swap are not found:
systemctl status multipathd.service
* multipathd.service - Device-Mapper Multipath Device Controller
Loaded: loaded (/usr/lib/systemd/system/multipathd.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Condition: start condition failed at Thu 2015-05-07 11:49:11 CEST; 7min ago
ConditionPathExists=/etc/multipath.conf was not met
and exit to dracut shell.
The multipathd package might install a service and a socket
file. Using the original service file from the installed
system without the socket file triggers a bug in systemd,
causing systemd to crash.
As we don't actually need to socket file in the initrd we
should be installing our own service file which does not
reference the socket file at all.
