commit ee569be4d6189a68b38d2af162af00ff475b48e2
Author: Yann Leprince <yann.leprince@ylep.fr>
Date: Wed Dec 21 14:32:54 2016 -0500
Fix boot dependency in systemd service file
From: Yann Leprince <yann.leprince@ylep.fr>
This fix ensures that a separate /var partition will be mounted before
rpcbind tries to write its status to /var/run.
Acked-by: NeilBrown <neilb@suse.com>
