The issue seems to be that I created directory "files" under
/var/lib/cobbler. Taking out the exception handling from config.py reveals:
Starting cobbler daemon: Traceback (most recent call last):
File "/usr/bin/cobblerd", line 76, in main
api = cobbler_api.BootAPI(is_cobblerd=True)
File "/usr/lib/python2.6/site-packages/cobbler/api.py", line 130, in
__init__
self.deserialize()
File "/usr/lib/python2.6/site-packages/cobbler/api.py", line 795, in
deserialize
return self._config.deserialize()
File "/usr/lib/python2.6/site-packages/cobbler/config.py", line 263,
in deserialize
serializer.deserialize(item)
File "/usr/lib/python2.6/site-packages/cobbler/serializer.py", line
122, in deserialize
rc = storage_module.deserialize(obj,topological)
File
"/usr/lib/python2.6/site-packages/cobbler/modules/serializer_catalog.py", line
229, in deserialize
datastruct = deserialize_raw(obj.collection_type())
File
"/usr/lib/python2.6/site-packages/cobbler/modules/serializer_catalog.py", line
174, in deserialize_raw
fd = open(old_filename)
IOError: [Errno 21] Is a directory: '/var/lib/cobbler/files'
renaming that to something else fixes the issue, though I still wonder
what is the logic...
