Serf does not start from cloudynitzar.sh because PUBLIC_IP is not found in /etc/init.d/serf:
ip addr show dev eth0 called from /etc/init.d/serf can have the work "dynamic" or not between "global" and "eth0". (below examples cloudy4 and cloudy5)
but in /etc/init.d/serf the condition PUBLIC_IP=$(ip addr show dev $SERF_INTERFACE|grep "global.* $SERF_INTERFACE\$"|awk '{print $2}'|awk -F "/" {'print $1'})
only works for the case without "dynamic" (case cloudy5), in case of cloudy4 the variable PUBLIC_IP is empty (because of "dynamic") and serf does not start.
It seems using PUBLIC_IP=$(ip addr show dev $SERF_INTERFACE|grep "global.*"|awk '{print $2}'|awk -F "/" {'print $1'}) without $SERF_INTERFACE\$ would capture the same line.
Cases: Cloudy4 does not work, cloudy5 works.
