33# When using 'zfs destroy -R' on a file system hierarchy that includes a
34# snapshot and a clone of that snapshot, and the snapshot has been
35# defer-destroyed, make sure that the 'zfs destroy -R' works as expected.
36# In particular make sure that libzfs is not confused by the fact that the
37# kernel will automatically remove the defer-destroyed snapshot when the
38# clone is destroyed.
39#
40# 1. Create test environment.
41# 2. Create a clone of the snapshot.
42# 3. 'zfs destroy -d <snap>'
43# 4. 'zfs destroy -R'
44# 5. Verify that the snapshot and clone are destroyed.
