# DESCRIPTION:
#
# ZFS has two mechanisms dealing with space for datasets, namely
# reservations and quotas. Setting one should not affect the other,
# provided the values are legal (i.e. enough space in pool etc).
#
# STRATEGY:
# 1) Create one filesystem
# 2) Get the current quota setting
# 3) Set a reservation
# 4) Verify that the quota value remains unchanged
#
