Hmm. First of all, I'm trying to get rid of the PID file, as with it 
it's quite hard to start multipathing when /var/run isn't mounted.
Plus it's not actually needed; everything can be done via multipathd 
-k nowadays.

So may I suggest to use
ExecReload=/sbin/multipathd -k'reconfigure'

here?
And do we actually need
PIDFile=
for systemd?
If not I'd rather remove that line, too.

Cheers,

Hannes
