35# DESCRIPTION:
36# A reservation of 'none' (which is an alias for 0) should be allowed. This
37# test verifies that is true.
38#
39# STRATEGY:
40# 1. Create a new file system in the test pool.
41# 2. Set the reservation to 'none'.
42# 3. Verify the associated reservation is indeed 0.
43# 4. Repeat with reservation set to 0.
