41# DESCRIPTION:
42# Verify that device nodes are modified appropriately during zfs command
43# operations on volumes.
44#
45# STRATEGY:
46# For a certain number of iterations, with root setup for each test set:
47#   - Recursively snapshot the root.
48#   - Recursively rename the snapshot 3 times.
49#   - Destroy the root.
50#
51#   - Recursively snapshot the root.
52#   - Clone the volume to another name in the root.
53#   - Rename the root.
54#   - Destroy the renamed root.
55#
56#   - Recursively snapshot the root.
57#   - Send|Receive the root to another root.
58#   - Destroy the original and received roots.
59#
60# At each stage, the device nodes are checked to match the expectations.
61#
62# TESTABILITY: explicit
63#
64# TEST_AUTOMATION_LEVEL: automated
65#
66# CODING_STATUS: COMPLETED (2008-03-04)
