Actually, the issue seems to be that the code (utils.py) is looking for files
by the name fence_*.template
powertemplate = "/etc/cobbler/power/fence_%s.template" % powertype
whereas the actual file names under /etc/cobbler/power are power_*.template.
If the power_*.template files are deprecated, why are they installed as part of
2.2.3? Also, are you saying that even though power_*.template is deprecated,
just renaming them to fence_*.template, the exact same files are OK to use?
Thanks
