helios-build onu fails when lipkg zones present

When running the onu subcommand to install my build of Helios when lipkg zones are present on the system I get the following error.

ry@masaka:~/helios$ ./helios-build onu -t helios-router-dev1

Start by reproducing the ./helios-build onu -t helios-router-dev1 command on a system with lipkg zones and trace the ONU handling around the pkg -R ... change-facet step. The work is done when ONU completes without the linked-image errors for the affected zones.
