Why does spacewalk-splice-checkin fail with error "KeyError: 'network.hostname'" ?

Issue

• Is it possible to configure SAM enhanced reporting without Satellite ?
• splice-sync fails with error:

# su - splice -s /bin/bash
-bash-4.1$ spacewalk-splice-checkin --splice-sync
Traceback (most recent call last):
