Ok. Let's look at fedora-storage-init.service and
ExecStart=/lib/systemd/fedora-storage-init from initscripts in Fedora,
for example.
We see in fedora-storage-init

if ! strstr "$cmdline" nompath && [ -f /etc/multipath.conf ] && \
                [ -x /sbin/multipath ]; then
        modprobe dm-multipath > /dev/null 2>&1
        /sbin/multipath -v 0
        if [ -x /sbin/kpartx ]; then
                /sbin/dmsetup ls --target multipath --exec
"/sbin/kpartx -a -p p" >/dev/null
        fi
fi

it would be easier to see it as
[Unit]
ConditionKernelCommandLine=!nompath
ConditionPathExists=/etc/multipath.conf
ConditionPathExists=/sbin/multipath
ConditionPathExists=/sbin/kpartx

[Service]
ExecStartPre=modprobe dm-multipath
ExecStart=/sbin/multipath -v 0
ExecStart=/sbin/dmsetup ls --target multipath --exec "/sbin/kpartx -a
-p p" >/dev/null

but it will not work :(
