  36 # DESCRIPTION:
  37 #
  38 # ZFS has two mechanisms dealing with space for datasets, namely
  39 # reservations and quotas. Setting one should not affect the other,
  40 # provided the values are legal (i.e. enough space in pool etc).
  41 #
  42 # STRATEGY:
  43 # 1) Create one filesystem
  44 # 2) Get the current quota setting
  45 # 3) Set a reservation
  46 # 4) Verify that the quota value remains unchanged
  47 #
