Everything you're trying to do should be handled by the default snippets,
you should not need to modify them.
For future reference though, when you see an un-rendered $SNIPPET in your
final output it means you've got a template error, which can usually be
diagnosed by looking at /var/log/cobbler/cobbler.log for an error message,
something like this:
Sun May 26 23:41:18 2013 - WARNING |
[{'code': u'VFFSL(SL,"SNIPPET",False)(\'hosts.xml\')',
'exc_val': NotFound(u"cannot find 'interfaces'",),
'lineCol': (28, 3),
'rawCode': u"$SNIPPET('hosts.xml')",
'time': 'Sun May 26 23:41:18 2013'},
{'code': u'VFFSL(SL,"SNIPPET",False)(\'networking.xml\')',
'exc_val': NotFound(u"cannot find 'hostname'",),
'lineCol': (38, 3),
'rawCode': u"$SNIPPET('networking.xml')",
'time': 'Sun May 26 23:41:18 2013'}]
(the above is from me troubleshooting why opensuse builds no longer seem to
be working...)
