| # DESCRIPTION: |
| # 'zpool events -f' should successfully follow new events. |
| # |
| # STRATEGY: |
| # 1. Clear all ZFS events |
| # 2. Run 'zpool events -f' in background, saving its output to a temporary file |
| # 3. Generate some ZFS events |
| # 4. Verify 'zpool events -f' successfully recorded these new events |
