21# DESCRIPTION:
22# 'zpool events -f' should successfully follow new events.
23#
24# STRATEGY:
25# 1. Clear all ZFS events
26# 2. Run 'zpool events -f' in background, saving its output to a temporary file
27# 3. Generate some ZFS events
28# 4. Verify 'zpool events -f' successfully recorded these new events
