Subject: [PATCH] rhel: Fix reload of OVS_USER_ID on startup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

OVS_USER_ID was being picked up from a previously existing
openvswitch.useropts rendering innefective any configuration change
through sysconfig.

There is no explicit ordering between Exec* and Environment* stanzas of
systemd, full enviroment is always reloaded before each Exec. We make
sure that openvswitch.useropts is removed first so that a fresh
OVS_USER_ID can be picked up from config.
