rinstall hangs if error in nodeset

[gurevichmark]

rinstall command hangs if nodeset detects a problem with diskless image:

root@c910f03c05k10:~/c910env/hardware_admin/stanzas/frame3# rinstall zztop osimage=rhels7.4-ppc64le-netboot-compute -V
[c910f03c05k10]: Provision node(s): zztop

[c910f03c05k10]: zztop: Did you run "genimage" before running "packimage"? kernel cannot be found at /install/netboot/rhels7.4/ppc64le/compute/kernel on c910f03c05k10
[c910f03c05k10]: Failed to generate grub2 configurations for some node(s) on c910f03c05k10. Check xCAT log file for more details.

Need to ^C to break out.
