# Sanity check default value may not be in list key
# RFC 7950:
# 7.6.1 The usage of the default value depends on the leaf's closest ancestor node in the
#       schema tree that is not a non-presence container (see Section 7.5.1):
# 7.8.2 any default values in the key leafs or their types are ignored.
#             v non-presence container (presence false) DEFAULT
# ancestor--> ancestor --> leaf --> default
# ^leafs closest ancestor that is not a non-presence container
# Test has three parts where system is started three times:
# 1) with init
# 2) with startup: r1 only
# 3) with startup: p4 only

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