Encounter error when install SONiC image if there are some onie_discovery variables assigned with multiple values inside machine.conf
- How I did it
Replace original ". /machine.conf" method and add another function to do the same thing.
- How to verify it
Add a item inside /host/machine.conf like onie_disco_ntpsrv=10.254.141.10 10.254.141.131
Do sonic_installer install to check if any error occurs
