gmeta-installer now gives out multiple scripts which are driven from the master node. This bug does not apply in this new scenario

suggestion -

there are two types of actions what happen in the dest-hdd-out.sh

1. communication with master node
2. local work

sometimes communication with master and local work are linked, sometimes not.

dest-hdd-out.sh starts with a state where

do_local_work=1

any local work is done by checking do_local_work == 1 in every point.

communication with master node happens all the time no matter what.

wherever currenlty 'quit' or 'quit_udp' are there, replace that with do_local_work=0

some places need careful handling where communictaion with master and local work are linked (e.g udp-receiver | tar -x)

when dest-hdd-out.sh fails at a particular point before post-install, then it exits immeidately,
but master node is waiting for a barrier to do post-install and continues to wait indefinitely.

dest-hdd-out.sh should handle the situation by partiticipating in the broadcast (and other udpcast operations) but having no effect on the system (>/dev/null) so that master node does not block.
