# Default handling and datastores.
# There was a bug with loading startup and writing it back to candidate/running
# where default mode in startup being "explicit" was transformed to "report-all"
# according to RFC 6243.
# Ie, all default values were populated.
# This test goes through (all) testcases where clixon writes data back to a datastore, and
# ensures default values are not present in the datastore.
# XXX two errors:
# 1. Running is changed
# XXX 2. type default not set

# Magic line must be first in script (see README.md)
