That's valid YAML. YAML can sometimes go into "flow-layout" mode, and
that's legal. Here's a quick test program:
import yaml
classes = [1,2]
params = [3,4]
newdata = {
"classes" : classes,
"parameters" : params
}
str = yaml.dump(newdata)
print str
print yaml.load(str)
===================================
[mdeh...@mdehaan cobbler]$ python /tmp/test.py
classes: [1, 2]
parameters: [3, 4]
{'classes': [1, 2], 'parameters': [3, 4]}
===================================
Is Puppet choking on this? Our YAML library has options to prevent this
if needed.
