OVERRIDES
---------
In some special cases, you would like to create an already defined object
with different parameters. In normal situations this leads to an error in cdist.
If you whish, you can mark this second definition of an object with
CDIST_ALLOW_OVERRIDE=true to tell cdist, that this object override is
wanted and should be accepted.
ATTENTION: Only use this feature if you are 100% sure in which order
cdist encounter the affected objects, otherwhise this results
into an undefined situation.

# for example in the inial manifest
# reate user account foobar with some hash for password
__user foobar --password 'some_fancy_hash'
# ... many statements and includes in the manifest later ...
# somewhere in a conditionaly sourced manifest
# (e.g. for example only sourced if a special application is on the target host)
# this leads to an error ...
__user foobar --password 'some_other_hash'
# this tells cdist, that you know that this is an override and should be accepted
CDIST_ALLOW_OVERRIDE=true __user foobar --password 'some_other_hash'
