1. The service startup is not working due to typo in dcae2_install.sh:

curl -k $NEXUS_REPO/org.onap.demo/boot/$ARTIFACTS_VERSION/dcae2_vm_init.sh -o /opt/dcae2_vm_init.sh
curl -k $NEXUS_REPO/org.onap.demo/boot/$ARTIFACTS_VERSION/dcae2_serv.sh -o /opt/dcae2_serv.sh
chmod +x /opt/dcae2_vm_init.sh
chmod +x /opt/dcae2_serv.sh
mv /opt/dcae2_serv.sh /etc/init.d
update-rc.d dcae_serv.sh defaults**

>> should be :
update-rc.d dcae2_serv.sh defaults**

2. Additionally another bug found in that script: missing parameter in NOFLOAT option

...
echo " address $DCAE_IP_ADDR" >> /etc/network/interfaces
...

$DCAE_IP_ADDR is not defined in script

 3. /opt/config/oam_network_cidr.txt is not defined (missing in NOFLOAT HEAT yaml file

CIDR=$(cat /opt/config/oam_network_cidr.txt)
BITMASK=$(echo $CIDR | cut -d"/" -f2)
